Abstract (in Japanese) (See Japanese page) 
(in English) We propose a low-power non-precharge-type two-port SRAM for video processing. The proposed memory cell (MC) has ten transistors (10T), comprised of the conventional 6T MC, a readout inverter and a transmission gate for a read port. Since the readout inverter fully charges/discharges a read bitline, there is no precharge circuit on the read bitline. Thus, power is not consumed by precharging. Besides, charge-less structure shortens a cycle time by 38% compared with the conventional SRAM, because it does not require a precharge period. Compared to the conventional 8T SRAM, the proposed SRAM reduces 81% of a charge/discharge possibility on the bitlines, and saves 74% of a readout power when considered as an H.264 reconstructed-image memory. The area overhead is 14.4% in a 90-nm process technology.
