Introduction

Beiyou Zhao is a prominent inventor based in Hefei, China. He has made significant contributions to the field of memory testing technologies, holding a total of 3 patents. His work focuses on developing methods and devices that enhance the efficiency and accuracy of memory testing.

Latest Patents

Zhao's latest patents include a "Method and device for testing memory with instruction signal." This invention provides a method and device for memory testing, along with a computer-readable storage medium. The method involves sending an instruction signal to the memory, which includes a randomly generated write or read instruction. A valid Column Address Strobe (CAS) instruction is randomly inserted before the instruction signal to ensure its proper execution. Additionally, at least one redundant CAS instruction or an invalid command is generated and inserted to test the memory's functionality.

Another notable patent is the "Memory chip test method and apparatus, medium, and device." This method involves sending a mode register write command to a memory chip to control its entry into a test mode of Write Clock to clock leveling (Wck2ck Leveling). The process includes setting a first preset time, sending a read and write clock signal after waiting, and determining a predicted value of the Wck2ck Leveling. The test value obtained from the memory chip is then compared to the predicted value to assess the chip's functionality.
