PROBLEM TO BE SOLVED: To provide a memory system that facilitates cost reduction, a method of controlling the same, and an information processor that uses the same.SOLUTION: A memory system comprises: a plurality of memory chips 18-1 and 18-2 which are arranged by lamination and electrically connected with each other by buses 20 (including an address bus, a data bus, and a control bus) that extend in a laminated direction while penetrating each chip; and a memory controller 16 that is connected to a plurality of processors 12a and 14a and is also connected to the bus 20, and to which a chip select signal line 22 for outputting a chip select signal to each of the memory chips 18-1 and 18-2 is connected. The memory controller 16 converts an address signal, which is output from each of the processors 12a and 14a, into a combination of the chip select signal and an address signal that is to be output to the bus 20, so as to relay data input/output between each of the processors 12a and 14a and each of the memory chips 18-1 and 18-2. |
