INFORMATION STORAGE DEVICE, INFORMATION STORAGE METHOD, AND INFORMATION STORAGE PROGRAM

摘要

A synchronous information storage device that controls the operation timing using a synchronous clock and exhibits improved performance through highly efficient operation processing and reduced power consumption of feature of DRAMs. The information storage device comprises a plurality of memory cells in which data is stored by storing electrical charges; and an amplifier that amplifies the charges of the memory cells, wherein a synchronous clock is used to time the input/output of the data. This information storage device performs two operations, that is, a charge extraction operation that extracts electrical charges transferred from the memory cells to the amplifier or a charge storing operation that stores charges from the amplifier into the memory cells and an input/output operation of the amplifier from/to a unit external to the information storage device, using the single clock of the synchronous clock for the timing.
