ABSTRACT:
An enhanced digital signal processing random access memory device utilizing a highly density DRAM core memory array integrated with an SRAM cache and internal refresh control functionality which may be provided in an integrated circuit package which is pin-compatible with industry standard SRAM memory devices. The memory device provides a high speed memory access device of particular utility in conjunction with DSP processors with performance equivalent to that of SRAM memory devices but requiring a significantly small die size which allows for the provision of greater effective memory capacity per die area. The internal refresh functionality of the device provides for all refresh operations to the DRAM memory array to occur transparently to the device user and provides control signals alerting the associated controller when refresh operations are being performed.
