Abstract
A random access memory (RAM) containing 256 memory cells organized as two pages, each page containing 16 8-bit wide working registers. RAM row address circuitry as well as read-write and page-select circuitry are provided. A fixed transistor static RAM cell is used as the memory cell. Double rail transfer of data is employed. The memory cells and bit lines associated with each of the two pages is interweaved in the array so that the precharged circuitry and the RAM input/output circuitry associated with each of the pages is alternately configured on the chip.
