摘要:
An MCP type semiconductor memory device having a defective cell remedy function, enables easy design and manufacture while minimizing chip area increase. The semiconductor memory device includes memory chips and a memory controller chip that designates an address of a memory chip according to an access request received from outside and controls access to the designated address. Each memory chip includes first and second storage regions and an information holder that holds address information representing associations between addresses in the first and second storage regions. The memory controller chip includes an address translating part that performs, upon receiving a request to access a specific address in the first storage region indicated by the address information, address designation by translating the specific address in the first storage region to an address in the second storage region corresponding to the specific address based on the associations represented by the address information.
摘要:
An MCP type semiconductor memory device having a structure in which a stack memory chip including a plurality of stacked memory chips and a memory controller chip are juxtaposed on a substrate, which achieves a reduction in package size. The semiconductor memory device includes a stack memory chip including a plurality of stacked memory chips, a substrate on which the stack memory chip is provided, and a memory controller chip adjacent the stack memory chip on the substrate. The stack memory chip is constructed such that an upper memory chip is stacked so as to shift toward a mounting position of the memory controller chip relative to a memory chip immediately below the upper memory chip. At least a part of the memory controller chip is received within a space between the substrate and a part of the stack memory chip that protrudes toward the memory controller chip.
摘要:
A resin molded type semiconductor device has an inner portion sandwiched between two outer surfaces. The device includes a chip support with a first, inwardly facing surface and a second, outwardly facing surface. The device also includes a semiconductor element with a first, inwardly facing surface and a second, outwardly facing surface. The respective first surfaces of the chip support and semiconductor element are fixed to each other. A mold resin is provided to seal the entire semiconductor device except for the respective second surfaces of the chip support and semiconductor element which remain exposed as part of the two outer surfaces of the device, in order to keep the semiconductor device thin.
