Abstract
Described herein are methods and apparatuses for write-assist voltage generation and power-down voltage scaling for static random access memory (SRAM) cells. According to various embodiments, an SRAM cell may include a local power supply voltage node for receiving a power supply voltage generated by a power supply voltage generator circuit, the generated power supply voltage being substantially equal to or less than a global power supply voltage provided to one or more transistors of the SRAM cell during a write-enable or power-down mode.
