VDD modulated sram for highly scaled, high performance cache

摘要

The present invention provides a device and method for fast SRAM reading and writing. A boost voltage source is provided, wherein the boost voltage source operates to increase a conductance of a latch device in the SRAM cell relative to a conductance of an access device in the SRAM cell. By virtue of the increased relative conductance between the latch and access devices (beta ratio), the access device may be assume a wider width without jeopardizing the read stability of the cell.
