Abstract

Official abstract text for this publication.

An apparatus comprising a memory and a controller. The memory may be configured to (i) implement a cache and (ii) store meta-data. The cache may comprise one or more cache windows. Each of the one or more cache windows comprises a plurality of cache-lines configured to store information. The controller is connected to the memory and configured to (A) process normal read/write operations in a first mode and (B) process special read/write operations in a second mode by (i) tracking a write followed by read condition on each of said cache windows and (ii) discarding data on the cache-lines associated with the cache windows after completion of the write followed by a read condition on the cache-lines.
