A 4-kB 500-MHz 4-T CMOS SRAM using low-VTHN bitline drivers and high-VTHP latches.

The design and physical implementation of a prototypical 500-MHz CMOS 4-T SRAM is presented in this work. The latch of the proposed SRAM cell is realized by a pair of cross coupled high-VTHP pMOS transistors, while the bitline drivers are realized by a pair of low-VTHN nMOS transistors. The wordline...
