摘要:
PROBLEM TO BE SOLVED: To provide a semiconductor memory device that can support various apparatuses and systems where high performance and lower power consumption are required, and has wide input-output of a multi-channel interface, and to provide a semiconductor package including the same. SOLUTION: The semiconductor memory device includes a semiconductor die including a plurality of memory cell arrays and an input-output bump pad part in the center of the semiconductor die. The input-output bump pad part provides a plurality of channels for connecting each of the memory cell arrays independently to an external device. The semiconductor memory device may adopt the wide input-output interface of the multi-channel and thereby achieving reduction in operating frequencies and expansion in band width. Thus, both the support and reduction in power consumption of the high performance apparatuses and systems, are achieved. COPYRIGHT: (C)2011,JPO&INPIT
