Abstract:
1. An information storage device comprising: a plurality of memory cells configured to store data by accumulating an electrical charge; and an amplifier configured to amplify the electrical charge of the memory cells, wherein a synchronizing clock signal is used for input/output timing of the data; and wherein an electrical charge removal operation for moving the electrical charge of said memory cells to said amplifier or an electrical charge accumulation operation for acquiring the electrical charge from said amplifier and accumulating the electrical charge of said memory cells and an input/output operation for said amplifier in relation to the outside of the information storage device are processed while using a single clock of said synchronizing clock signal for synchronization timing, wherein said operations begin when a request signal is received; and wherein, when said request signal is received, the address of a memory cell related to the request signal is compared against the address of data temporarily retained in said amplifier at the time of request signal reception.
