摘要：The present invention provides a memory device that can flexibly decide thedata to be preread. The memory device according to the present invention includes: a

nonvolatile memory; a buffer memory having a higher access speed than the nonvolatilememory; and a control circuit. The control circuit creates a preread data managementtable that associates a logical address of preread data specified by a preread commandinputted from the outside and a buffer memory address for storing the preread data.Moreover, the control circuit reads data specified by the command from the nonvolatilememory and stores it in the buffer memory as preread data. When a logical addressspecified in a read command inputted from the outside matches a logical addressassociated by the preread data management table, the control circuit outputscorresponding preread data from the buffer memory.
