Latest Patents

Weirong Chen's latest patents include a memory system capable of reducing reading time. This invention features a bias circuit that comprises a first current generator, a second current generator, and a bit line bias generator. The first current generator is designed to produce a first replica charging current based on the charging current flowing through a voltage bias transistor. The second current generator generates a first replica cell current according to a cell current flowing through a common source transistor. The bit line bias generator is connected to a first page buffer and is responsible for generating a bit line bias voltage, which is supplied to the first page buffer based on a comparison of the first replica charging current and the first replica cell current.

Another notable patent by Chen is also a memory system aimed at reducing reading time. This system includes a charging current reproduce unit, a cell current reproduce unit, a current comparator, and a bit line bias generator. The charging current reproduce unit generates a charging reference voltage based on the charging current flowing through a voltage bias transistor. The cell current reproduce unit creates a cell reference voltage according to a cell current flowing through a common source transistor. The current comparator consists of a first current generator that produces a replica charging current based on the charging reference voltage, and a second current generator that generates a replica cell current based on the cell reference voltage. The bit line bias generator then generates a bit line bias voltage to control a page buffer for charging a bit line according to the difference between the replica charging current and the replica cell current.
