It is low the dissipation power die memory circuit and outside power source

机译:低功耗的芯片存储电路和外部电源

摘要

PPROBLEM TO BE SOLVED: To provide a low power consumption dynamic random access memory which reduces current consumption as a DRAM by an external signal and does not malfunction in the case of small current consumption. PSOLUTION: An input circuit 240 in which a signal is inputted, a memory array 260 which holds data and a peripheral circuit 250 which controls the memory array are driven by internal power sources from internal power source circuits 220, 270 and an output circuit which outputs the signal is driven by an external power source 210. The internal power source circuits 220, 270 are inactivated in response to a control signal CONT to be inputted from the outside and an output circuit is controlled at a high impedance state while the external power source is supplied.
