Semiconductor device and semiconductor package including the semiconductor device

A semiconductor device comprising:

• a cell area in which a plurality of memory cells are arranged in an array structure;
• and
• a peripheral area in which circuits configured to drive the memory cells are arranged, the peripheral area being next to the cell area,
• wherein:
• the cell area is divided into a plurality of banks,
• the plurality of banks comprise first banks having a base size and second banks having a size of 1/(2*n) (wherein n is an integer greater than or equal to 1) of the base size, the plurality of banks being arranged in a first direction and a second direction perpendicular to the first direction, and
• the semiconductor device has a shape of a rectangular chip which is elongated in the second direction.

A semiconductor package comprising:

• a package substrate;
• a first stack structure in which a plurality of chips are stacked, the first stack structure being mounted on the package substrate;
• a second stacked structure in which a same number of chips as that of the first stack structure are stacked, the second stacked structure being mounted on the package substrate and arranged to be horizontally adjacent to the first stacked structure;
• and
• a sealing material sealing the first stacked structure and the second stacked structure on the package substrate,
• wherein each of the plurality of chips comprises a cell area in which a plurality of memory cells are arranged in an array structure and a peripheral area in which circuits configured to drive the plurality of memory cells are arranged, the peripheral area being next to the cell area,
• wherein the cell area is divided into a plurality of banks,
• the plurality of banks comprise first banks having a base size and second banks having a size of 1/(2*n) (wherein n is an integer greater than or equal to 1) of the base size, the plurality of banks being arranged in a first direction and a second direction perpendicular to the first direction, and
• each chip of the plurality of chips has a shape of a rectangular chip which is elongated in the second direction.
