概要

This paper describes design techniques for a high-throughput BiCMOS self-timed SRAM. A new BiCMOS read circuit using a pipelined read architecture and a BiCMOS complementary clocked driver (BCCD) are proposed to reduce the operating cycle time. A 8192×9-b dual-port self-timed SRAM designed using the proposed techniques achieved a clock cycle time of 3.0 ns, that is, a 333-MHz operating frequency, by SPICE simulation on model parameters for 0.8-μm BiCMOS technology. A high-speed built-in self-test (BIST) circuit was studied and designed for the 3.0-ns cycle SRAM. It is confirmed that the BIST circuit allows the 3.0-ns cycle SRAM to test at its maximum operating frequency.
