Abstract

A dynamic MOS random-access memory is described which includes a circuit for permitting checking of the on chip refresh counter. The memory also includes a refresh generator, the frequency of which automatically varies to compensate for temperature variations. Other innovations include an arbitration circuit, a hidden refresh function and unique accessing of redundant lines.
