GENERIC PHYSICAL LAYER PROVIDING A UNIFIED ARCHITECTURE FOR INTERFACING WITH AN EXTERNAL MEMORY DEVICE AND METHODS OF INTERFACING WITH AN EXTERNAL MEMORY DEVICE

A generic physical layer providing a unified architecture for interfacing with an external memory device. The physical layer comprises a transmit data path for transmitting a parallel data to the external memory device and a receive data path for receiving a serial data from the external memory device. The generic physical layer is characterized by a receive enable logic for masking strobe of the serial data, wherein the transmit data path and the receive data path each comprising a FIFO circuit, a data rotator and an adjustable-delay logic for delay tuning and a per-bit-deskew for multi-lane support.
