Novel 7T sram cell for low power cache design
Low-power on-chip cache is a crucial part in many applications. Conventional write operation depends on discharging/charging large bit lines capacitance which causes high power consumption. We propose a 7T SRAM cell that only depends on one of the bit lines during a write operation and reduce the write power consumption. HSPICE simulation shows that at least 49% write power saving, higher stability, and no performance degradation with additional 12.25% silicon area
