Abstract

Techniques pertaining the designs of memory controller are disclosed. According to one aspect of the present invention, a memory controller reduces delays in a data strobe signal of a DDR memory relative to a clock signal of a memory controller thereof. In one embodiment, the memory controller employs four IO ports, two inverters, six edge triggers and a multiplexer. By feeding back an inverted clock signal and utilizing the rising and filing edges of the clock signal, the delays in a data strobe signal of a DDR memory relative to a clock signal of a memory controller are considerably reduced or minimized.
