Device and method for achieving SRAM output characteristics from DRAMS
A method is provided for achieving SRAM output characteristics from DRAMs, in which a plurality of DRAMs are arranged connected in parallel to a controller in such a way as to be able to obtain SRAM output characteristics using the DRAMs, comprising a process in which data is output to an external device when a control signal for data reading has been input from the external device, by sequentially repeating a step in which the controller sends a data output state control signal to one DRAM and sends a refresh standby state control signal to the other DRAMs, the data is read and sent to the external device from the DRAM in the output state, and a refresh standby state control signal is sent to the DRAM which was in the output state while an output state control signal is sent to another DRAM and data is read out from the DRAM in the output state, and a step in which the controller sends a control signal for changing the output state to the refresh standby state.
