Official abstract text for this publication.
A method for data storage in a data storage system, which includes a main storage device and a non-volatile memory, includes assessing quality levels of respective memory blocks of the non-volatile memory. One or more of the memory blocks whose assessed quality levels are lower than a predefined quality threshold are identified. The identified memory blocks are assigned to serve as read cache memory. Data is read from the main storage device via the read cache memory, including the assigned memory blocks.
Opening claim text (preview).
The invention claimed is: 1. A method for data storage, comprising: in a data storage system that includes a main storage device and a non-volatile memory, assessing a respective quality level of each memory block of a plurality of memory blocks of the non-volatile memory; identifying a first subset of memory blocks of the plurality of memory blocks, wherein the quality level of each memory block of the first subset of memory blocks is less than a predefined quality threshold;…
