Abstract
A memory circuitincludes bit cellsselected for reading with a word line voltage upon a word line. Word line voltage control circuitrygenerates a two-step word line voltage signal. The word line voltage first increases to an intermediate level at which word line transistorsweakly couple the bit cellto the bit lines. This intermediate level is maintained for a first delay period. After the first delay period, the word line voltage is increased to a full rail value and this full rail value maintained for a second delay period. The word line voltage is then returned to a low level at the end of the read operation. This two-step word line voltage signal provides a better access disturb margin for the bit cell
