ABSTRACT:
A flash memory device having a page buffer circuit providing a shared resource between a flash array controller circuit and a user. The page buffer circuit comprises a Plane A and a Plane B, wherein each of the planes A and B is a static random access memory array. The page buffer circuit further comprises a mode control circuit for enabling access to the planes A and B over a host bus in a user mode and access to the planes A and B by the flash array controller in a flash array controller mode.
