<p>PURPOSE: To improve the throughput of programming to a flash memory device by sharing a page buffer circuit between a flash array controller circuit and a user. CONSTITUTION: A page buffer circuit 70 is composed of planes A and B, and in this case, the planes A and B respectively mount static random access memory(SRAM) arrays. Further, the page buffer circuit 70 has a mode control circuit for enabling access through a host bus to the planes A and B in a user mode and access to the planes A and B depending on a flash array controller in a flash array controller mode.</p> |
