Title: Innovations by Cheow F Yeo
Introduction
Cheow F Yeo is a notable inventor based in San Jose, CA, who has made significant contributions to the field of memory circuits. With a total of 5 patents to his name, Yeo's work focuses on enhancing data bandwidth and memory efficiency.
Latest Patents
One of his latest patents is the "Pump Control Circuit," which describes a dynamic random access memory circuit that achieves much higher data bandwidth. This is accomplished by maximizing the number of memory cell rows that are held open and by indefinitely increasing the time that the rows remain open. The boosted voltage of a pump circuit is directed to active rows based on the presence of a pump token, which is located in a circular shift register corresponding to a memory array. The concurrence of the token and a pump-enable signal allows the array to receive a boosted voltage independent of an array-select operation.
Another significant patent is the "Apparatus and Method for Writing to Multiple Addresses." This invention involves a memory array that includes multiple columns, each containing a predetermined number of memory cells. A write driver generates a signal that facilitates writing data to one or more memory cells. The write data line, along which signals propagate to selected memory cells, includes several column nodes. The columns are divided into groups, with each group containing columns bearing consecutive column addresses, optimizing the writing process.
