Using bit errors from memory to alter memory command stream

A system, method, and memory controller are provided that alters a memory command stream to a hardware memory. Data is written to the hardware memory and, after the data is stored in the memory, error correction code is received from the memory. Bit errors are identified based upon the error correction code that was received. The memory command stream is then altered based upon the number of bit errors that were identified. In one embodiment, altering the memory command stream includes adjusting a memory refresh rate, while in another embodiment, altering the memory command stream includes adjusting a memory usage delay.
