Embodiment Construction
[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0022] 1. Lamination of semiconductor memory devices
[0023] figure 1 It is a schematic perspective view of an example of three-dimensional mounting of a stacked semiconductor memory device according to an embodiment of the present invention. In this semiconductor memory device, four identical memory cell array chips C1-C4 are laminated to obtain a memory capacity that is four times the average area. These chips C1 to C4 correspond to the chip layer of the present invention.
[0024] In the chips C1 to C4, a plurality of chip select pads CS1, CS2 and one chip enable pad CE are respectively formed. Also, for simplicity in figure 1 It is not recorded in , but other pads necessary for storage operations, such as address or I / O, control pads, etc., are also formed. The number of chip select pads can be taken arbitrarily according to the number of stacked chips. In th...
