MEMORY WITH WORD LINE ACCESS CONTROL

摘要

A memory having a memory array having a plurality of word lines, a plurality of bit cells coupled to the word lines, and a plurality of control memory cells coupled to the word lines. Each word line of the plurality of word lines has a control memory cell coupled thereto and each control memory cell has an output. The memory also has a plurality of logic circuits coupled to the plurality of word lines. The output of each control memory cell is coupled to a corresponding one of the plurality of logic circuits. The plurality of logic circuits prevents access to the word line selected by a row address if the output of the control memory cell coupled to the selected word line is in a first logic state.
