Memory system and assembling method of memory system

摘要

According to one embodiment, each memory chip included in a memory package includes a first storage unit that stores therein first information that is n-bit information and is a comparison target of a chip address, and is used for identifying its own memory chip, a second storage unit that stores therein second information for determining an effective bit of the n-bit first information, and a control unit that determines an effective bit of the n-bit first information and an effective bit of the chip address based on the second information.

主权项

1. A memory system comprising:
a memory package including a plurality of memory chips, each of the memory chips including a non-volatile memory cell array; and a controller configured to select one memory chip from the memory package based on a chip enable and a chip address, wherein each of the memory chips includes a first storage unit configured to store therein first information that is n-bit information (n is an integer of 2 or more) compared to the chip address, the first information being used for identifying its own memory chip, a second storage unit configured to store therein second information for determining an effective bit of the n-bit first information, and a control unit configured to determine an effective bit of the n-bit first information and an effective bit of the chip address based on the second information.
