ABSTRACT:
A dynamic random access memory obtains improved access time for reading data from a multiplicity of memory cells along a given selected row. This is obtained by allowing the output data line to remain active between activations of a column enable signal. An increase in data valid time at the memory output is obtained, while allowing increased latitude in memory address setup time.
