ABSTRACT:
A Unified Memory Architecture (UMA) using intelligent media memory provides an improved way of solving the granularity and memory bandwidth problems in the electronic computer memory system. A specially designed memory chip is attached to an existing attachment point of the system by integrating the bus interface on the memory chip. The memory chip additionally integrates on-chip data-intensive computation functions with the dynamic random access memory (DRAM) macros. Two system attachment points for the new integrated DRAM and logic chip are disclosed; the first using the local central processing unit (CPU) bus interface, and the second using a combination of the main memory bus and an alternative system bus such as a Peripheral Component Interconnect (PCI) bus.
