    摘要: A semiconductor memory device having a memory plane defined by a plurality of memory cells, a decoder line for accessing the memory cells, a common data line on which a signal output from an accessed memory cell is collected, and a sense amplifier for amplifying the signal collected on the common data line. The sense amplifier has an amplifying circuit portion which is composed of a pair of common-collector type bipolar transistors supplied with the signal collected on the common data line as a differential input, and a plurality of MOS transistors for converting a change in current into a change in voltage. Each of the MOS transistors has a lightly-doped drain structure.

    摘要: A semiconductor memory is provided with automatic refresh means including a timer, a refresh counter and a refresh buffer each formed on a semiconductor chip mounted with an asynchronous memory, for automatically performing a periodic refresh operation on the basis of a basic clock signal which is generated in response to the detection of a logical change in the output of the refresh counter. The automatic refresh counter includes means for performing one of a read operation and a write operation which are based upon a regular address signal asynchronous with the periodic refresh operation, in preference to the periodic refresh operation.
