Title: Lakshmi Neeharika Gamini and DDR SDRAM Calibration

Introduction

Lakshmi Neeharika Gamini is an inventor associated with Bengaluru, India, and Qualcomm Incorporated. Her patent work addresses memory-system calibration, with a focus on improving the timing relationship between data signals in DDR SDRAM.

Latest Patents

The provided information lists one patent for Gamini: “Double Data Rate Synchronous Dynamic Random Access Memory (‘DDR SDRAM’) Data Strobe Signal Calibration.” The invention calibrates phase skew between the data strobe (DQS) and data (DQ) signals. During system-level memory tests, the device adjusts the DQ driver’s impedance to impair impedance matching on the DQ channel, steps through a range of phase-skew values, and records an error count for each test. The tests can emulate mission-mode operation. The device then selects the phase skew associated with the lowest error count and applies a corresponding DQS delay during subsequent mission-mode operation. The listed patent count is 1 patent.

Career Highlights

Gamini’s listed invention concerns a practical challenge in memory-device operation: calibrating signal timing to reduce errors. The supplied information associates her with Qualcomm Incorporated but does not provide further details about her role or career history.
