Abstract
A computer-implemented method, according to one embodiment, includes: retrieving a physical block address corresponding to a logic block address, extracting information from the physical block address, and performing a lookup operation in cache using the extracted information. A range check of the physical block address is further performed in response to the lookup operation succeeding, while data is read from the cache in response to the range check succeeding. An architecture of the cache supports separation of data streams, as well as parallel writes to different non-volatile memory channels. The cache architecture further supports pipelining of the parallel writes to different non-volatile memory planes. Moreover, the non-volatile memory controller is configured to perform a direct memory lookup in the cache based on a physical block address.
