In view of the remarkable progress in MPU performance, improvement in the data rate of L2 cache SRAMs is desirable to maximize system performance. As a solution, Double-Data-Rate (DDR) SRAMs, which can realize an I/O frequency of up to twice that of conventional Single-Data-Rate (SDR) SRAMs, have been reported. Increase in operation-current due to higher operation frequency causes severe power-line noise and heating. Therefore, reduction of operation-current is an important issue in designing high-speed SRAMs. In order to realize both high-frequency operation and power reduction, we propose new sense circuitry and a bit-line load scheme.
