A 90MHz 16M bit System Integrated Memory with Direct Interface to CPU

摘要

This paper describes a system integrated memory with direct interface to CPU which integrates an SRAM, a DRAM and control circuitry including a TAG. This system memory realizes a computer system without glue chips. Thus, this system memory brings a computer system which is low cost, low power and compact size with sufficient performance. The maximum operating frequency is 90MHz and the operating current at cache hit is 156mA.
