Abstract
A memory system is connectable to a host having a host memory and includes a non-volatile memory that stores management data, a memory controller configured to manage caching of parts of the management data in cache lines of the host memory, and a first memory configured to store a bitmap that includes a bit indicating whether the memory controller has accessed first data stored in the host memory after power was last supplied to the memory system. The first data indicates whether or not a part of the management data corresponding thereto is stored in one of the cache lines, and the memory controller is configured to perform either a first operation of reading the first data from the host memory or a second operation of reading an initial value of the first data managed by the memory controller, based on the bitmap.
