Flash memory device supporting cache read operation

摘要

A flash memory device comprises a non-volatile memory core operatively connected to first and second buffer memories through a page buffer. The device further comprises a first register adapted to receive command and address information from a host system, a copy circuit adapted to copy the command and address information from the first register to a second register within a control logic circuit. The device alternately transfers information to the first and second buffer memories during a cache read operation comprising a plurality of data read operations.
