INTEGRATED CIRCUIT DEVICE AND INTEGRATED CIRCUIT WITH HIGH-SPEED NON-VOLATILE MEMORY DATA TRANSFER CAPABILITY

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit device for improving the speed of transferring data between a random access memory device and a non-volatile memory device.;SOLUTION: The integrated circuit device is provided with a RAM array including a plurality of columns of RAM cells therein and a plurality of first bit lines electrically connected to the plurality of columns of RAM cells, a non-volatile memory array including a plurality of columns of non-volatile memory cells therein and a plurality of second bit lines electrically connected to the plurality of columns of non-volatile memory cells, and a data transfer circuit electrically connected to the plurality of first and second bit lines. The data transfer circuit has a bidirectional direct data transfer capability between the plurality of first bit lines and the plurality of second bit lines in the case of transferring RAM data from the plurality of first bit lines to the plurality of second bit lines while transferring non-volatile memory data from the plurality of second bit lines to the plurality of first bit lines.;COPYRIGHT: (C)2008,JPO&INPIT
