Abstract
A computer-implemented method of cache replacement includes steps of: determining whether each cache block in a cache memory is a read or a write block; augmenting metadata associated with each cache block with an indicator of the type of access; receiving an access request resulting in a cache miss, the cache miss indicating that a cache block will need to be replaced; examining the indicator in the metadata of each cache block for determining a probability that said cache block will be replaced; and selecting for replacement the cache block with the highest probability of replacement.
