Latest Patents

Among Shantanu Gupta's recent innovations are two notable patents:

1. **Systems and Methods for Retaining Inflight Data During a Power Loss Event**

This patent introduces memory devices capable of maintaining the state of existing memory blocks during a power loss event. The SSD controller suspends the program operation as soon as a power loss is detected, allowing inflight data to be re-sent directly to NAND latches. This process ensures data reliability by programming the inflight data to a newly erased page using single pulse programming, without the need to ramp down existing programming voltages.

2. **Aggressive Quick-Pass Multiphase Programming for Voltage Distribution State Separation in Non-Volatile Memory**

This invention outlines a multiphase programming scheme that enhances the margin between voltage distributions of memory cells. By applying a series of program pulses, the scheme ensures better data recovery in case of power loss events through aggressive quick pass approaches, leading to improved performance in data storage systems.
