SRAM cell with read buffer controlled for low leakage current

摘要

A functional memory of the integrated circuit includes row and column periphery units and an array of memory cells having a core storage element and a read buffer. The functional memory further includes a read buffer supply line that is connected to the read buffer, wherein the read buffer supply line is switchable between an operating mode output and a low-power mode output of a read buffer supply that is separate from core storage element supplies.
