Abstract
Increasing the storage capacity of high-performance signal processors while maintaining the original RAM cell necessitates modification of the entire lay-out of the circuit. The invention relates to the once-only design of peripheral circuitry which provides control of blocks of 4 full CMOS RAM cells (easy to process) or 9 double-layer polysilicon cells (more difficult to process, but having smaller dimensions). It is defined in the RAM peripheral circuitry whether all 9 cells can be accessed (memory capacity from 2.sup.xx n to (2.sup.xx (n+1)+2.sup.xx (n-2)) or 8 cells can be accessed (memory capacity from 2.sup.x n to 2.sup.xx (n+1).
