Title: The Innovative Contributions of Ran Wang

Introduction

Ran Wang is a prominent inventor based in Irvine, California. He has made significant contributions to the field of non-volatile memory technology, holding a total of 11 patents. His work has advanced the understanding and functionality of memory systems, making him a key figure in the industry.

Latest Patents

Among his latest patents is the "Dual stage sensing for non-volatile memory," which describes a method and apparatus for accessing a non-volatile memory cell. This invention involves a memory block that provides a plurality of memory cells arranged into rows and columns. A read circuit is configured to read a selected row of the memory block by concurrently applying a control voltage to each memory cell along the selected row. For each column, a respective local sense amplifier and a column sense amplifier are used to successively differentiate a voltage across the associated memory cell in that column to output the programmed content of the row. Another notable patent is the "Spin-transfer torque memory non-destructive self-reference read method." This method includes applying a first read current through a magnetic tunnel junction data cell to form a first bit line read voltage. The method then applies a second read current through the same data cell, with the first read current being less than the second. The first bit line read voltage is compared with the second bit line read voltage to determine whether the first resistance state of the magnetic tunnel junction data cell was a high resistance state or low resistance state.
