USE OF ERROR CORRECTION POINTERS TO HANDLE ERRORS IN MEMORY

摘要

Methods, apparatuses, and systems related to use of error correction pointers (ECPs) to handle hard errors in memory are described herein. In embodiments, a read module of a memory controller may read a codeword stored in a memory. The read module may determine a number of hard errors in the codeword. Responsive to a determination that the number of hard errors exceeds a threshold, the read module may store ECP information associated with the hard errors. The read module may include an error correction code (ECC) module to perform an ECC process on the codeword. The read module may use the ECP information to decode the codeword to recover the data responsive to a determination that the ECC process failed. Other embodiments may be described and claimed.

1. An apparatus for reading data from a memory, the apparatus comprising:
a read module configured to:
determine if a number of hard errors in a codeword read from memory exceeds a threshold; andresponsive to a determination that the number of hard errors in the codeword exceeds the threshold, store error correction pointer (ECP) information associated with hard errors of the codeword in one or more ECPs.
