Abstract
A memory device that performs internal ECC (error checking and correction) can selectively return read data with application of the internal ECC or without application of the internal ECC, in response to different read commands from the memory controller. The memory device can normally apply ECC and return corrected data in response to a normal read command. In response to a retry command, the memory device can return the read data without application of the internal ECC.
