Abstract
A system including a plurality of NAND flash memory devices each having a NAND flash interface, where the NAND flash interface of each NAND flash memory device includes an 8-bit data bus, and a memory controller configured to exchange data with the plurality of NAND flash memory devices via the 8-bit data bus. The memory controller is further configured to select a first NAND flash memory device of the plurality of NAND flash memory devices, without using a Chip Enable signal of the NAND flash interface, by transmitting, on the 8-bit data bus, an identification byte identifying the first NAND flash memory device. The memory controller is further configured to transmit, on the 8-bit data bus, a command byte to the first NAND flash memory device. The first NAND flash memory device is configured to perform an operation indicated by the command byte.
