See full text

An apparatus comprising a memory and a controller. The memory is configured to process a plurality of read/write operations. The memory comprises a plurality of memory modules. Each memory module has a size less than a total size of the memory. The controller is configured to (i) classify data from multiple blocks of the memory as hot-read data or non hot-read data, (ii) aggregate the hot-read data to dedicated blocks, and (iii) select a type of error correcting code to protect the hot-read data in the dedicated blocks. The aggregation reduces an impact on endurance of the memory.
