Abstract:
|
The SRAM which functions as the cache for
system-on-chip is vital in the electronic industry. The heavy bitand
data-line capacitances are the major road blocks to its
performance. A high-performance SRAM is proposed using a 1.8
V/0.18 μm CMOS standard process from Chartered
Semiconductor Manufacturing Ltd (CHRT). It incorporates a
discharging mechanism that helps eliminating the waiting time
during the read operation, hence offering a faster sensing speed
and lower power consumption. Our post-layout simulation
results have shown that it improves the sensing speed and power
consumption by 51.4%, and 62.47%, respectively when compared
with the best published design. The total Power-Delay-Product
(PDP) is 81.79% better. Furthermore, it can operate at a supply
voltage as low as 0.8 V with a high stability to the bit-line
capacitances variation and mismatch. |
