Abstract
Rows of a memory array are segmented into a predetermined number of word line groups. Each row in a word line group has a word line disposed between parallel power supply lines. Each of the power supply lines in a row of a word line group is shared by an adjacent row in the word line group. A row on a boundary of a word line group has a power supply line shared by a row on a boundary of an adjacent word line group. All power supply lines in a word line group are at a full power voltage in response to one of the rows in the word line group being selected by a word line. Most power supply lines in an adjacent word line group are at a full power voltage. All power supply lines in other word line groups are at a power-gated voltage.
