Abstract
A memory controller having an error checking and correction (ECC) circuitry can detect an error in data being read from memory and correct that error with a retry flow without needing to send another read to the memory for the data. The read data is stored in a read data buffer (RDB) at the memory controller when the read data is received from memory. The memory controller has an error detection path from the RDB to the host and an error correction path. Read data that has no errors can be sent directly to the host. Instead of flushing the RDB in response to the error detection, the memory controller executes a retry flow, where the RDB provides the read data to the error correction path for error correction.
