US Patent 8099564 Programmable memory controller

A memory controller implemented within a programmable integrated circuit can include a user interface having a command register and a plurality of data First-In-First-Out (FIFO) memories, wherein the command register can receive an address of a data FIFO memory of the plurality of data FIFO memories. A core controller coupled to the user interface can, responsive to an instruction from the user interface, generate control signals that initiate an operation within a memory device coupled to the core controller. A physical layer coupling with the core controller, the user interface, and the memory device can, responsive to a read operation of the memory device, store data received from the memory device within the selected data FIFO memory according to the address received in the command register.
