Abstract
A multi-port DRAM having refresh cycles interleaved with normal read and write operations implements a single cycle refresh sequence by deferring the write portion of the sequence until the next refresh cycle. During a single clock cycle, the system writes stored data from a refresh buffer into a row in the memory array and then reads data from one row of the memory array into the buffer.
