MCP Memory

1.0 Product Introduction

NAND Flash Memory has addresses multiplexed into 8 I/Os(x16 device case : lower 8 I/Os). This scheme dramatically reduces pin counts and allows sys-

tem upgrades to future densities by maintaining consistency in system board design. Command, address and data are all written through I/O's by bringing

WE to low while CE is low. Those are latched on the rising edge of WE. Command Latch Enable(CLE) and Address Latch Enable(ALE) are used to mul-

tiplex command and address respectively, via the I/O pins. Some commands require one bus cycle. For example, Reset Command, Status Read Com-

mand, etc require just one cycle bus. Some other commands, like page read and block erase and page program, require two cycles: one cycle for setup

and the other cycle for execution. Page Read and Page Program need the same five address cycles following the required command input. In Block

Erase operation, however, only the three row address cycles are used. Device operations are selected by writing specific commands into the command

In addition to the enhanced architecture and interface, the device incorporates copy-back program feature from one page to another page without need

for transporting the data to and from the external buffer memory. Since the time-consuming serial access and data-input cycles are removed, system per-

formance for solid-state disk application is significantly increased.
