Title: Innovations by Alfred K Chan

Introduction

Alfred K Chan is a notable inventor based in Milpitas, CA (US). He has made significant contributions to the field of memory cache technology, holding 2 patents that enhance system performance and efficiency.

Latest Patents

His latest patents include a "Random access cache memory controller and system" and "Cache including decoupling register circuits." The first patent describes a memory cache apparatus that is compatible with various bus transfer types, including both non-burst and burst transfers. In burst mode, it supports a 'demand word first' wrapped around quad fetch order. This cache memory system decouples the main memory subsystem from the host data bus, allowing for parallel cache-hit and system memory transfer operations. This design increases system speed and hides system memory write-back cycles from the microprocessor. It also accommodates differences in the speed of local and system buses and provides an easy migration path from non-burst to burst mode microprocessor-based systems. Various memory organizations are supported, including direct-mapped, two-way set associative, and four-way set associative.

The second patent also focuses on a memory cache apparatus that includes a random access memory, a host port, and a system port. It features an input register for selectively writing data to the random access memory and an output register for receiving data from the random access memory. This design further enhances system speed and accommodates various memory organizations.
