Introduction
Rak-Joo Sung is a notable inventor based in Suwon-si, South Korea. He has made significant contributions to the field of memory devices, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is for a TCAM device and operating method thereof. This ternary content addressable memory (TCAM) device includes a memory cell that comprises a data storage circuit, a limiter circuit, and a discharge circuit. The data storage circuit features a first resistor and a second resistor connected in series to divide a voltage corresponding to search data, which is configured to store cell data. The limiter circuit receives the divided voltage through an input terminal and transmits an output voltage through an output terminal based on the level of the divided voltage. The discharge circuit discharges a matching line that indicates whether the stored cell data matches the search data, based on the output voltage of the limiter circuit.
Another significant patent by Rak-Joo Sung involves a memory device driving matching lines according to priority. This memory device includes a storage circuit, a first driving circuit, and a second driving circuit. The storage circuit stores first data and compares it with second data. The first driving circuit selectively drives a matching line to a first logic state, depending on the comparison result of the first data and the second data by the storage circuit. The second driving circuit drives the matching line to a second logic state regardless of the comparison result.
