Title: Innovations of Jungyong Lee

Introduction

Jungyong Lee is a prominent inventor based in San Jose, California, known for his significant contributions to memory circuit technology. With a total of 10 patents to his name, he has made remarkable advancements in the field of memory systems.

Latest Patents

One of his latest patents is focused on a memory bitcell with column select functionality. This innovation includes systems and methods that enhance the column selection capabilities of memory circuits. The design incorporates additional series pass gates, such as junction sharing transistors, which are coupled with a column select signal to create an integrated column select port. This port allows each bitcell to achieve column select functionality while improving area and power performance compared to traditional methods. However, the added column select port can introduce challenges such as increased area, column select load, and potential degradation of writability due to charge-sharing effects. To address these issues, some embodiments propose sharing intermediate nodes among adjacent bitcells and incorporating additional ground-connected transistors to enhance writability and read noise margin.

Another notable patent by Jungyong Lee is related to clock-skew-tolerant memory updating. This invention provides robust memory updating capabilities in high-speed memory circuits. During each memory update interval, the update of a pre-memory with un-validated data begins upon detecting a potential match between a tag memory and a key. However, the update data is not deemed valid until a determination is made according to a delayed clock. This process ensures that un-validated data is only written out as validated update data once a data valid indication is generated.
