Common high and low random bit error correction logic

A memory buffer device comprising:

• a read data interface configured to receive data read from a memory address corresponding to a location on one of a plurality of memory devices, each of the plurality of memory devices characterized as one of a high random bit error rate (RB ER) memory device and a low RBER memory device;
• and
• common error correction logic configured to detect and correct error conditions in data read from both high RBER memory devices and low RBER memory devices, the common error correction logic comprising:
• a plurality of error correction units which provide different complexity levels of error correction and have different latencies, the plurality of error correction units comprising a first fast path error correction unit for isolating and correcting random symbol errors, a latency of the first fast path error correction unit less than a latency of an other of the plurality of error correction units.

A method comprising:

• receiving data read from a memory address corresponding to a location on one of a plurality of memory devices located coupled to a memory module, each of the plurality of memory devices characterized as one of a high random bit error rate (RB ER) memory device and a low RBER memory device;
• executing common error correction logic using the received data as input to generate corrected data, the common error correction logic configured to detect and correct error conditions in both high random symbol error rate (RBER) memory devices and low RBER memory devices, the common error correction logic comprising a plurality of error correction units which provide different complexity levels of error correction and have different latencies, the plurality of error correction units comprising a first fast path error correction unit for isolating and correcting random symbol errors, a latency of the first fast path error correction unit less than a latency of an other of the plurality of error correction units;
• and
• outputting the corrected data to a requestor of the data.
