Title: Innovations of Inventor Wen-Ming Lee

Introduction

Wen-Ming Lee is a prominent inventor based in Miaoli County, Taiwan. He has made significant contributions to the field of dynamic random access memory (DRAM) technology. With a total of 8 patents to his name, Lee continues to push the boundaries of innovation in memory apparatus design.

Latest Patents

One of his latest patents is titled "Control circuit and control method for controlling delay lock loop in dynamic random access memory." This invention involves a DRAM that includes a delay lock loop (DLL), a clock tree, an off-chip driver (OCD), a phase detector (PD), and a filter. The DLL receives a reference clock and updates a delay line, outputting a calibrated clock via the clock tree. The PD detects a phase difference between the calibrated clock and the reference clock, while the filter activates the DLL to update the delay line based on this phase difference. Notably, when a READ command is received, the filter increases the number of activations for the DLL to shorten the access time of the DRAM.

Another significant patent is "Memory apparatus and voltage control method thereof." This invention describes a memory apparatus that includes a synchronous circuit, a clock tree, and a memory controller. The synchronous circuit generates a clock signal from a reference clock, while the clock tree assigns this clock signal to multiple signal paths. The memory controller adjusts the frequency of the clock signal according to the operating mode of the memory apparatus.
