Title: Ruili Zhang: Innovator in Memory Technology

Introduction

Ruili Zhang is a prominent inventor based in Folsom, CA (US). She has made significant contributions to the field of memory technology, holding a total of 7 patents. Her innovative work focuses on enhancing memory performance and efficiency.

Latest Patents

One of her latest patents is for a writing bit alterable memory. This technology includes current generators located in the periphery outside the main memory core. The current is generated in the periphery and driven into the core, which reduces the capacitance effect on memory cells. The current generation utilizes the chip supply voltage, which is then mirrored using a pump voltage. In certain embodiments, the mirroring is ratioed at the partition level and multiplied at the plane level. A delay is incorporated before applying the currents to the cell to accommodate transients.

Another notable patent is for a level shifter circuit. This circuit features first and second supply inputs for receiving different supply voltages. It includes a shifting circuit that receives an input voltage and outputs one of the supply voltages based on the input value. The shifting circuit comprises a circuit branch with a series of electronic devices and a voltage dropper device, which introduces a voltage drop. Additionally, the level shifter circuit has a bias generator that produces a bias voltage for the voltage dropper device, depending on the supply voltage values.
