Please combine Fig. 2 with reference to figure 3 and Fig. 4.Fig. 3 is for according to one embodiment of present invention, the schematic diagram of the flash memory device identifier of first three byte of serial NOR flash memory device (flash memory device ID), the logical sequence schematic diagram that Fig. 4 is serial flash memory device.As shown in Figure 3, first three byte of flash memory device ID is comprised of the vendor identification symbol (manufacture ID is below called vendor id) of a byte and the device identifier of two bytes (device ID).The device ID of one byte represents the type of memory of serial NOR flash memory device, and another byte device ID represents the memory span of serial NOR flash memory device.In this embodiment, 16 hex value ' 20h ' of vendor id are only example, can not be in order to limit the scope of the invention.Similar, 16 hex value ' BBh ' (corresponding stored device type) and 16 hex value ' 16h ' (corresponding stored device capacity) do not form restriction of the present invention.The vendor id and the device ID that it should be noted that serial NOR flash memory device can not be 16 hex value ' 00 ' or 16 hex value ' FF '.
As shown in Figure 4, serial flash memory device 250 is in serial NOR flash memory device situation, and serial flash memory device 250 can see through signal wire SI and for example receive instruction IR(, reads READ instruction).At instruction IR(, for example read READ instruction) move into serial flash memory device 250 after, the flash memory device ID(of serial flash memory device 250 for example, the serial NOR flash memory device in this embodiment) can shift out at once (shift out).More specifically, byte B[0]-B[i] can be after instruction IR sends at once processed unit 220 receive, byte B[0] at other bytes B[1]-B[i] and between be received, other bytes B[1]-B[i] represent the vendor id of serial flash memory device 250 and byte B[1] and B[2] represent the device ID of serial flash memory device 250.In addition, the value ' 15 '-' 0 ' of device ID (that is, byte B[1] and B[2]) represent to there are 16 bits, wherein, the Most Significant Bit of the table of bits showing device ID of respective value ' 15 ' (Most Significant Bit, MSB).The byte quantity that note that the flash memory device ID of serial NOR flash memory is not limited with 3.
Incorporated by reference to Fig. 2, combine with reference to figure 5 and Fig. 6.Fig. 5 is the schematic diagram of the first two byte of the flash memory device ID of serial nand flash memory device according to one embodiment of present invention, and Fig. 6 is for being the logical sequence schematic diagram of serial nand flash memory device.As shown in Figure 5, the first two byte packet of the flash memory device ID of serial flash memory device is containing the vendor id of a byte and the device ID of a byte.In this embodiment, each all illustrates 16 hex value ' 2Ch ' (corresponding vendor id) and 16 hex value ' 12h ' (corresponding intrument ID) in order to example, is not intended to limit the scope of the invention.It should be noted that the vendor id of serial nand flash memory device and any type of device ID can not be all 16 hex value ' 00 ' or 16 hex value ' FF '.
As shown in Figure 6, in the situation that serial flash memory device 250 is serial nand flash memory device, serial flash memory device 250 can see through signal wire SI and for example receive instruction IR(, read READ instruction).At instruction IR(for example, read READ instruction) move into serial flash memory device 250 and in fact virtual (dummy) byte can not do any action by processing unit 220(processing unit 220) send (sent) afterwards, serial flash memory device 250(is serial flash memory device in this embodiment for example) flash memory device ID can shift out at once, wait to be sent.More specifically, byte B[0]-B[i] can receive at once processed unit 220, after instruction IR and dummy bytes are received, wherein, byte B[1] represent the vendor id of serial flash memory device 250, byte B[2] represent the device ID of serial flash memory device 250, and byte B[0] corresponding dummy bytes, wherein, byte B[0] at byte B[1] and B[2] receive before, and byte B[0] data template can comprise a plurality of bits, each bit has an identical binary values (for example, 16 hex value ' 00 ' or ' FF ').Note that when dummy bytes sends, serial flash memory device 250 can not exported any byte, therefore, byte B[0] data template can depend on acquiescence and drive and set, this acquiescence drives the output signal of setting for serial flash memory device 250.In addition, dummy bytes can be produced by the level (that is, the bit value ' 0 ' of dummy bytes shown in Fig. 6) of pulldown signal, or does not do any action (that is, the bit value ' 0 ' of dummy bytes can become high-impedance state) and produce.As the value ' 7 '-' 0 ' (that is, byte B[2]) of installing ID) representative has 8 bits, and wherein, the bit of respective value ' 7 ' represents the MSB of device ID.Note that the byte data of type of flash memory device of serial nand flash memory device is not as limit.
As mentioned above, any byte of the vendor id of serial NOR/NAND flash memory device and device ID can be not equal to 16 hex value ' 00 ' or ' FF ', and before the mobile device chip shown in Fig. 2 receives flash memory device ID, serial nand flash memory device can read dummy bytes.Therefore, in the situation that serial flash memory device shown in word Fig. 2 250 is serial nand flash memory device, received front 3 bytes of the processing unit 220 shown in Fig. 2 (being the device ID shown in byte, vendor id and Fig. 6 of corresponding dummy bytes) are unequal each other.In addition, in all current serial NOR flash memory devices, vendor id is not equal to device ID.Therefore,, the in the situation that of serial NOR flash memory device, it is unequal each other that the serial flash memory device 250 shown in Fig. 2 receives front 3 bytes (that is, 1 byte vendor id shown in Fig. 4 and the device ID of 2 bytes).In brief, see through and detect the similarity that has received byte, processing unit 220 can determine whether serial flash interface 230 is connected to serial flash memory device.
More particularly, when determining that serial flash interface is connected to serial flash memory device, the specified byte in received byte can be compared with tentation data template, to determine the type of serial flash memory device.Please refer again to Fig. 2, Fig. 4 and Fig. 6.When serial flash memory device 250 is during for serial nand flash memory device, the byte receiving before other receive byte (that is, byte B[0]) has data template ' 00 ' or ' FF '.When serial flash memory device 250 is serial NOR flash memory device, however, the byte receiving before other bytes (that is, byte B[0]) represent vendor id, wherein, vendor id is not equal to data template ' 00 ' and ' FF '.Therefore, the type of serial flash memory device 250 can be according to receiving byte B[0]-B[i] in specified byte (that is, byte B[0]) and determine.In brief, can utilize flash memory device ID form between serial NOR flash memory device and serial nand flash memory device and the difference of the behavior of reading, with being connected of detection/recognition and interface.
