Abstract
Disclosed is an accumulation memory circuit for providing a fast read, modify, and write operation in a single clock cycle time. The memory circuit is configured to read data stored in the memory device at an address. The memory circuit includes a reconfigurable adder unit generating read, accumulate and write output in a single clock cycle. The memory circuit is further configured to minimize data overflow. A high speed accumulation method comprises resetting a memory circuit; reading from an address of the memory circuit; performing internal addition within the memory circuit and rewriting into the address of the memory circuit in a single clock cycle.
