Abstract
A circuit includes a memory having error correction, circuitry which initiates a write operation to memory. When error correction is enabled and the write operation to the memory has the width of N bits, the write operation to the memory is performed in one access to the memory, and when error correction is enabled and the write operation to the memory has the width of M bits, where M bits is less than N bits, the write operation to the memory is performed in more than one access to the memory. In one example, the one access to the memory includes a write access to the memory, and the more than one access to the memory includes a read access to the memory and a write access to the memory.
