Introduction

Rishabh Dubey is a prominent inventor based in Bengaluru, India. He has made significant contributions to the field of solid-state drive (SSD) technology, holding 2 patents that focus on improving data management in non-volatile memory systems.

Latest Patents

Rishabh's latest patents include innovative methods and apparatus for variable size logical page management based on hot and cold data. This invention provides a solution for managing a flash translation layer (FTL) in SSDs. The approach involves creating a logical to physical (L2P) table that separates frequently accessed hot data from less frequently accessed cold data. This separation reduces the size of the L2P table needed in RAM, leading to lower write amplification and latencies, particularly beneficial for large capacity SSDs.

Another notable patent by Rishabh focuses on implementing a logical to physical address mapping in SSDs. This invention manages the L2P table by storing it entirely in non-volatile memory (NVM) and partitioning it into multiple sections. The SSD is divided into front and back-end processing portions, allowing for efficient scheduling of read and write access to the NVM.
