Nand dummy read

WitrynaD in read and write access. For example, read operation can be performed in mode A and write in mode B. • If Extended mode is disabled, FMC operates in Mode1 or Mode2 as follows: – Mode 1 is the default mode when SRAM/ PSRAM memory type is selected (Bits 3:2 MTYP = 0x0 or 0x01 in the FMC_BCRx register). Witrynabelow 55nm node, however, the size of NAND flash string with dummy cell starts to become smaller than that of conventional NAND flash string, as shown in Fig. 7. It is because that the space between select transistor and edge memory cell in conventional NAND flash string becomes larger than 3F including the dummy cell and two space …
