PCI Express based dual-ported memory storage containing single port memory controller

摘要

A memory cartridge may include a memory controller that includes a single PCIe port and a PCIe switch. The PCIe switch may include a first PCIe port communicatively coupled to a first PCIe switch, a second PCIe port communicatively coupled to a second, another PCIe switch, and a third PCIe port communicatively coupled to the single PCIe port of the memory controller include. The first PCIe port and the second PCIe port may be configured to be selectively communicatively coupled to a non-transparent bridge (NTB) of the PCIe switch.
