  • Patent number: 11397689
    Abstract: A memory manager includes an internal memory and a hash function circuit. The internal memory includes a V2H (virtual address to hash function) table and an exception mapping table. The V2H table stores at least one virtual address group and a type information on a hash function mapped to the virtual address group. The exception mapping table stores at least one exception virtual address not translated into a physical address by the hash function in the virtual address group and a physical address mapped to the exception virtual address. The has function circuit checks, when a virtual address is provided from a host, type information on a hash function mapped to a virtual address group including the virtual address, by referring to the V2H table included in the internal memory. The has function translates the virtual address into a physical address by using the hash function corresponding to the type information.
