Configurable memory array

摘要

There is provided a memory system on a chip. The memory system includes a configurable memory having a first mode of operation wherein the configurable memory is configured as a cache and a second mode of operation wherein the configurable memory is configured as a local, non-cache memory. A selection of any of the first mode of operation and the second mode of operation is capable of being overridden by an other selection of an other of the first mode of operation and the second mode of operation. The configurable memory may be configured at manufacture time, at burn-in time, and/or during program execution. Moreover, an access mode of the configurable memory may be determined from an address corresponding to a memory access instruction.
