Title: Seung Cheol Oh: Innovator in Memory Technology

Introduction

Seung Cheol Oh is a prominent inventor based in San Jose, CA, known for his contributions to memory technology. With a total of 5 patents, he has made significant advancements in the field of semiconductor memory systems.

Latest Patents

One of his latest patents is titled "Test mode for a self-refreshed SRAM with DRAM memory cells." This invention provides a self-refreshing SRAM that includes internal DRAM memory cells, equipped with a test mode enable circuit. This circuit allows for testing the real refresh time of the SRAM memory cells and determining the maximum refresh capability of the internal DRAM memory cells. In normal operation, the test mode enable circuit remains inactive, while in test mode, it becomes active, allowing external command signals to control the memory logic.

Another notable patent is "DRAM with total self refresh and control circuit." This innovation enables the internal refreshing of one or more DRAM arrays without the need for additional external command signals. The scheduling of refresh cycles and read/write access cycles is managed by an arbitration and selection circuit, which receives input signals from an independent oscillator and a row access select signal. This system enhances the efficiency of DRAM operations by controlling the refresh power and managing the number of cells in each DRAM block.
