Abstract
A processor may comprise a cache, which may be divided into a first and second section while the processor operates in a low-power mode. A cache line of the first section may be fragmented into segments. A first encoder may generate first data bits and check bits while encoding a first portion of a data stream and a second encoder may, separately, generate second data bits and check bits while encoding a second portion of the data stream. The first data bits may be stored in a first segment of the first section and the check bits in a first portion of the second section that is associated with the first segment. The first decoder may correct errors in multiple bit positions within the first data bits using the check bits stored in the first portion and the second decoder may, separately, decode the second data bits using the second set of check bits.
