Abstract
Disclosed are techniques for storing data decompressed from the compressed pages of a memory block when servicing data access request from a host device of a memory system to the compressed page data in which the memory block has been compressed into multiple compressed pages. A cache buffer may store the decompressed data for a few compressed pages to save decompression memory space. The memory system may keep track of the number of accesses to the decompressed data in the cache and the number of compressed pages that have been decompressed into the cache to calculate a metric associated with the frequency of access to the compressed pages within the memory block. If the metric does not exceed a threshold, additional compressed pages are decompressed into the cache. Otherwise, all the compressed pages within the memory block are decompressed into a separately allocated memory space to reduce data access latency.
