Title: Semiconductor storage device
Inventor: AOYAMA KEIZO
IPC: G11C11/401
Filed: 1986-12-19
Abstract: PURPOSE:To reduce readout cycle time and readout access time, and to speed up readout operation by executing the preceding readout. CONSTITUTION:A read pointer means reads out data of an address which precedes data to be outputted originally, and stores it in a register. Accordingly, when a next readout command is inputted, data to be outputted is not sent out of a storage part but the data read out precedently from the register is sent out as output data. Also, at the time of readout reset, a selecting means is activated and the storage contents of '0' address of the storage part are read out and stored in the register, and accordingly, when the first readout clock is received, the stored data of '0' address to be read out is sent out. In such a way, a readout speed can be increased, and also, indefinite readout immediately after resetting a readout operation can also be prevented.
