Latest Patents

Lunkai Zhang's latest patents include a "Bypass buffer for worn out codewords" and a "Data storage device and method for hiding tweak generation latency." The bypass buffer patent addresses the issue of worn out codewords caused by stuck-at-failure bit errors and other endurance failures. It involves a controller that monitors the number of worn out bits in a codeword and corrects the associated data when a threshold is exceeded. The corrected data is then stored in a bypass buffer along with the memory address of the codeword. The second patent focuses on reducing latency in data decryption by generating a tweak value in parallel with the translation of logical addresses to physical addresses. This tweak value is stored in a tweak buffer until needed, enhancing the overall performance of the decryption process.
