Latest Patents

One of Tazunoki's latest patents is a special mode control method for dynamic random access memory. This innovation provides a data retention mode intended for low power consumption. In this mode, the current supply capabilities of voltage generation circuits are limited to maintain information retention in memory cells. Additionally, the number of selected memory mats in the data retention mode is increased compared to the normal read/write mode and refresh mode. Special modes, such as the data retention mode, are set by combining an address strobe signal with other control signals, and dummy CBR refresh is executed to release the special mode.

Another significant patent involves a wafer scale or full wafer memory system and its packaging method. This invention aims to achieve higher packaging density by vertically stacking wafers at predetermined intervals. The packaging technique is enhanced to allow for precise memory system layout realization and the formation of accurate through holes. Furthermore, other chips are fixed on the wafer to achieve even higher packaging density.
