Title: Semiconductor memory and its testing method
Inventor: TAKAHASHI HIROYUKI
IPC: G11C11/403
Filed: 2002-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory which has small chip size and small power consumption, is inexpensive, and causes neither delay of access nor memory destruction due to skew included in an address as a semiconductor memory which is equipped with the same memory cells as those of a DRAM and operates with SRAM specification. SOLUTION: An ATD circuit 3 generates a one-shot pulse in an address change detection signal ATD in response to change of an address Address supplied from outside. At this time, one-shot pulses are generated by the bits of the address and put together to generate only one one-shot pulse even when the address includes the skew. Refreshing operation is performed first during the generation period of the one-shot pulse by using a refresh address R- ADD generated by a refresh control circuit 4. Then a latch control signal LC is generated in response to the fall of the one-shot pulse and the address is supplied to a latch 2 to access a memory cell array 6.
