Latest Patents
One of Chih Hsueh's latest patents is titled "Efficient memory hierarchy in solid state drive design." This patent describes systems and methods for improving the performance and reliability of flash memory solid-state drive devices. The invention includes a flash memory array component that stores data and a memory hierarchy component that transfers data between the host and the flash memory array. The memory hierarchy features a level one (L1) cache coupled to a merge buffer, which is also connected to the flash memory array and the host. The L1 cache and merge buffer utilize volatile memory, while the memory hierarchy includes both write and read components for efficient data management.
Another significant patent by Hsueh is "Power safe translation table operation in flash memory." This invention provides systems and methods that ensure the accuracy of address translations in a memory system by decoupling the system address from the physical address. It records address-modifying transactions in a non-volatile write buffer, linking the last-in-time translation physical address with the current translated physical location. Additionally, integrity check protection is applied to the translation and written data, allowing for recovery of write operations that may not have fully completed due to errors.
