Title: Siddharth Bhatt: Innovator in Non-Volatile Storage Systems

Introduction

Siddharth Bhatt is a notable inventor based in Fremont, CA (US). He has made significant contributions to the field of non-volatile storage systems, particularly in enhancing the reliability of three-dimensional NAND technology. His innovative approach addresses critical issues related to latent defects in memory structures.

Latest Patents

Siddharth holds a patent titled "Prevention of latent block fails in three-dimensional NAND." This technology is designed to detect latent defects in non-volatile storage systems. The process involves applying a stress voltage to SGS transistors within a 3D memory structure. After the application of the stress voltage, the threshold voltage (Vt) of the SGS transistors is tested to ensure it meets specific criteria. If the Vt distribution falls outside the allowed range, a sub-block mode is activated. In this mode, data is not written to memory cells in a sub-block containing defective SGS transistors, thereby preventing data loss while preserving data capacity in unaffected areas.
