Title: Tetsuo Ashizawa: Innovator in Semiconductor Technology
Introduction
Tetsuo Ashizawa, a distinguished inventor based in Kawasaki, Japan, has made significant contributions to the field of semiconductor technology, holding a total of nine patents. His innovative approach to electronic design has paved the way for more efficient and powerful data transfer systems and memory storage solutions.
Latest Patents
One of Tetsuo Ashizawa's latest patents, titled "Semiconductor storage having different operation modes," introduces an SRAM macro that operates in both normal and low power modes. In normal mode, multiple memory-cell array blocks are accessible, while in low power mode, the bit lines within these blocks remain floating. When transitioning back to normal operation, the SRAM macro sequentially precharges only the bit lines of the blocks being accessed, effectively dispersing the peak precharging current.
Another notable patent is the "Data transfer system," which features two data transfer signal lines connecting transmitting and receiving sides. This innovation reduces power consumption even when the amount of data to be transferred increases. The transmitting side employs an encoder to manage signal potentials, while the receiving side utilizes a decoder to accurately output transferred data onto the designated signal lines.
