Efficient command mapping scheme for short data burst length memory devices
Abstract:
An exemplary system of the present disclosure comprises a memory controller, a command bus, a data bus, a memory device and a memory. The memory device is coupled to the memory controller by the command bus and the data bus. The memory stores instructions that when executed by the computer system perform a method of requesting data from the memory device. This method comprises receiving a plurality of commands for the memory device from the command bus, the memory device clocked by a clock. At least one command of the plurality of commands includes a first command and a second command within a single clock cycle of said clock. At least one of the first command and second command is a data access command. The first command is executed during a first clock cycle and the second command is executed during a second subsequent clock cycle.
