Abstract
An integrated circuit memory system includes a write-back buffer and a control circuit that support read-write-modify (RWM) operations within a high capacity memory device. A RWM operation may include reading from the integrated circuit memory device and the write-back buffer to identify whether the memory device or the write-back buffer has the data requested by a read instruction issued to the memory system. The data read from the write-back buffer is then written into the memory device and a modified version of the requested data is written to the write-back buffer in anticipation of subsequent transfer to the memory device.
