Title: Hiroyuki Koinuma: Innovator in Memory Technology
Introduction
Hiroyuki Koinuma is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of memory technology, holding a total of 18 patents. His work focuses on enhancing the performance and efficiency of memory systems, which are crucial for modern computing.
Latest Patents
One of Koinuma's latest inventions is a burst transfer memory. This innovative memory system comprises a first memory with a cell array arranged in a matrix and a second memory that performs random access operations at a higher speed than the first. The interface circuit controls both memories as a single burst transfer memory, allocating addresses as consecutive addresses. It initiates random access to both memories simultaneously, accessing the second memory before activating the word line of the first memory, and subsequently accessing a page of the first memory after activation.
Another notable patent is a semiconductor integrated circuit featuring both clock synchronous and clock non-synchronous type circuits. In this design, the clock non-synchronous circuit performs data read operations based on a read control signal. After a predetermined delay, the read data is latched in one of several latch circuits, selected based on a control signal rather than a clock signal. This ensures that a latch circuit is always selected after the read data is output.
