Summary :

A 4-way set associative TagRAM with 1.189-Mb capacity has been developed which can handle a secondary cache system of up to 16 Mbytes. A 9-ns cycle operation and clock to Dout of 4.7 ns are achieved by use of circuit techniques such as a pipelined decoding scheme, a single PMOS load BiCMOS main decoder, a BiCMOS sense-amplifying comparator, doubly placed self-timed write circuits, and highly linear VCO for a PLL. The device is successfully implemented with 0.7-µm double polysilicon double-metal BiCMOS technology.
