ABSTRACT:
A dynamic random access memory (DRAM) array is configured to appear to a host computer as a static random access memory (SRAM) array. This allows the use of a component which is functionally equivalent to an SRAM array, but which is less costly and which provides more memory in the same unit area. A temperature sensing circuit allows the DRAM array to use less power than would normally be possible by using a reduced refresh rate based on the temperature of the DRAM array. For example, instead of refreshing a 1 megabyte DRAM every 8 ms, refreshing the DRAM every 128 ms is possible, depending on the temperature of the DRAM array.
