Latest Patents

Chao-Jung Hung's latest patents include innovative methods for storing repair data in memory devices. One of his patents describes a method of storing repair data of a memory array in a one-time programming memory (OTPM). This method involves performing a first test and repair using a built-in self-test-and-repair (BISTR) module to determine initial repair data. The process includes loading this data into both a repair memory and a duplicated repair memory within the BISTR module. Following this, a second test and repair is conducted to ascertain additional repair data, which is then stored in the repair memory of both the BISTR module and the memory array. The method ensures that the output of the logic gate is stored in the repair memory of the memory array, ultimately leading to the storage of the repair memory content in the OTPM.

Another patent by Hung relates to a system for storing repair data of a random access memory (RAM) array in an OTPM. This system comprises a RAM array that includes a main memory, redundant rows and columns, and a first repair register memory. The BISTR module, equipped with a second repair register memory, is utilized to test and repair the RAM array. The OTPM is designed to store repair data from multiple test and repair stages, ensuring that the data from different stages is consolidated within the same data segment.
