摘要: A system for processing a read request for maximizing host read performance in a flash memory-based storage device is provided. The system for processing the read request solves a bottleneck phenomenon caused by a processor by adding an independent automatic read request processor, different from a conventional system in which a processor of a storage device processes the read request. Also, when processing the read request, a storage device using a write buffer may control a process of merging data of the write buffer and a flash memory and transmitting the data to a host based on a descriptor array, thereby minimizing processor overhead.
