Abstract
A programmable integrated circuit with memory interface circuitry is provided. The memory interface circuitry may include soft memory interface logic and hard memory interface logic. The soft memory interface logic may be implemented using programmable circuits, whereas the hard memory interface logic may be implemented using non-programmable dedicated circuits. The soft memory interface logic may include error correction code (ECC) encoder and decoder circuits and circuitry for carrying out a read modified write (RMW) operation. The hard memory interface logic may include a write data buffer, a read data buffer, and other circuitry for supporting the RMW operation. The soft memory interface logic is interposed between the hard memory interface logic and the user logic on the programmable integrated circuit.
