Title: Innovations of Yu-Hsuan Cheng
Introduction
Yu-Hsuan Cheng is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of data storage technology. With a total of 6 patents to his name, Cheng's work focuses on enhancing the reliability and efficiency of memory devices.
Latest Patents
Cheng's latest patents include a "Data storage apparatus and method for preventing data error using the same." This invention provides a data storage apparatus that includes a memory and a memory controller. The memory consists of multiple blocks, and the memory controller is designed to record a read count of a target block. It performs an error bit check on the free storage space of the target block when the read count meets a specific condition. If the check result is negative, it programs dummy data to the free storage space of the target block.
Another significant patent is the "Method for determining resistance calibration direction in ZQ calibration of memory device." This method involves repeatedly comparing a reference voltage with a target voltage to obtain a series of comparison outputs. A ZQ calibration controller determines the majority state of these outputs to establish a resistance calibration direction, which is then used to generate a calibration code for adjusting the target voltage.
