1. A memory access processing method based on memory chip interconnection, comprising implementing, by a first memory chip, a process comprising: receiving a memory access request; and sending, according to a preconfigured routing rule and through a chip interconnect interface disposed on the first memory chip, the memory access request to a second memory chip connected with the chip interconnect interface when the first memory chip is not a target memory chip corresponding to the memory access request, wherein the second memory chip is taken as the first memory chip for implementing the process, until the target memory chip corresponding to the memory access request is determined.
