The invention relates to the field of computer system structure and integrated circuit design, and a high-speed memory chip having a plurality of independent access channels is disclosed, including anon-chip memory and several high-speed serial access channels. A network-on-chip interconnect module is also included. The on-chip memory includes a plurality of memory sub-blocks accessible in parallel, and the memory sub-blocks and the high speed serial access channels are interconnected by the on-chip interconnect network module, and the on-chip interconnect network module being implemented ina single bus, a multi-bus, a ring network, a two-dimensional mesh, or a crossbar switch. The invention has a high-speed memory chip with a plurality of independent access channels, has good bandwidthexpansibility, realizes the shared parallel access of a plurality of main control chips to the memory chip and the data sharing and exchange among the plurality of main control chips, integrates storage and processing, and reduces the total storage cost of the system and the design and manufacture cost of the memory chip.
