Abstract: A method for providing a memory translation layer includes: receiving write request streams from a host computer; selectively storing each write request stream into a sequential zone, a K-associative zone, and a random zone of log blocks of a nonvolatile memory based on the characteristics. A first group of the write request streams that are sequential and start from a header page of a log block are stored in the sequential zone. A second group of the write request streams that are sequential but do not start from a header page of a log block are stored in the K-associative zone. A third group of the write request streams that are random are stored in the random zone.
