According to one embodiment, a memory system includes a chip including a cell array and first and second caches configured to hold data read out from the cell array; an interface configured to manage a first and a second addresses; a controller configured to issue a readout request to the interface; and a buffer configured to hold the data from the chip. The interface transfers the data in the first cache to the buffer without reading out the data from the cell array if the readout address matches the first address, transfers the data in the second cache to the buffer without reading out the data from the cell array if the readout address matches the second address, and reads out the data from the cell array and transfers the data to the buffer if the readout address does not match either one of the first or second address.
