Title:
セルフタイミング回路を有するスタティックメモリ
Document Type and Number:
Japanese Patent JP4339532
Kind Code:
B2
Abstract:
A static memory including a memory cell array having word lines, bit line pairs, and memory cells, each having a pair of nodes holding opposite levels; includes a dummy circuit disposed along the memory cell array, having a dummy word line, a dummy bit line pair, a self-timing dummy memory cell connected to the dummy word and bit lines and having a pair of nodes holding opposite levels, and load dummy memory cells connected to the dummy bit line pair; and a timing control circuit for detecting a voltage change of the dummy bit line pair to generate a start signal to a sense amplifier. The pair of nodes of the self-timing dummy memory cell are fixed to a first status, and the pair of nodes of the load dummy memory cell are fixed to a second status opposite to first status.
