Latest Patents

One of his latest patents is a method for testing embedded DRAM arrays. This innovative system includes DRAM blocks and a processor-based built-in self-test system. It generates a test data pattern for each DRAM block, performs a write of the test data pattern, pauses for a predetermined period, and then reads the resulting data pattern. The process ensures that the writing and reading operations are efficiently timed, with overlapping pauses for multiple DRAM blocks.

Another significant patent involves testing logic and embedded memory in parallel. This technique utilizes logic scan chain testing procedures alongside memory built-in self-test (BIST). It combines voltage isolation between memory and logic segments, as well as isolation between logic and memory test clocks. A test algorithm is introduced to manage the scan chain operation during BIST, enhancing the overall testing process.
