Latest Patents
One of his latest patents is titled "Write Data Protection at Emergency Power Off." This invention relates to an electronic circuit and method for backing up write cache data on DDR memory in data storage devices during an emergency power off (EPO). The method employs a power management integrated circuit (PMIC), a combo driver, and a MOSFET for regulator output. It involves detecting a voltage value that falls below a predetermined threshold, retracting a write head from a hard disk drive (HDD), backing up data, and resetting the HDD after the backup is complete. The process can occur in parallel or sequentially. The method utilizes spindle back-electromotive force (BEMF) power to ensure sufficient energy for the backup. If the spindle BEMF power is inadequate, the retraction is paused, and a high impedance is introduced to reduce the load until the BEMF recovers before the power on reset. This innovative approach ensures that backup data remains intact and is not lost due to power failure.
