SEMICONDUCTOR MEMORY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18589303 titled 'SEMICONDUCTOR MEMORY DEVICE
The semiconductor memory device described in the abstract features a sense amplifier situated between a memory cell array and an input/output circuit. The sense amplifier includes a data latch circuit operating at a first voltage, a multiplexer operating at a second voltage, and a sense amplifier unit.
- The data latch circuit has first and second nodes, with the first node connected to the multiplexer and latching a first voltage supplied from the multiplexer based on the data to be stored.
- The second node is linked to the sense amplifier unit and latches a second voltage that is the inverse of the first voltage.
- When the first voltage is supplied from the multiplexer, a high-level of the first voltage latched in the first node matches the second operating voltage level, transitioning to the first operating voltage level afterward.
Potential Applications: - This technology can be applied in various semiconductor memory devices to enhance data storage and retrieval processes. - It can improve the efficiency and speed of memory operations in electronic devices.
Problems Solved: - Enhances the speed and accuracy of data reading and writing in semiconductor memory devices. - Optimizes the performance of memory cells within the array.
Benefits: - Faster data processing and improved overall performance of semiconductor memory devices. - Enhanced reliability and efficiency in data storage and retrieval operations.

Original Abstract Submitted
A semiconductor memory device includes a sense amplifier provided between a memory cell array and an input/output circuit. The sense amplifier has a data latch circuit operating at a first operating voltage and having first and second nodes, a multiplexer operating at a second operating voltage, and a sense amplifier unit. The first node is connected to the multiplexer and latches a first voltage supplied from the multiplexer in accordance with data to be latched. The second node is connected to the sense amplifier unit and latches a second voltage having a voltage level that is inverted from that of the first voltage. A high-level of the first voltage latched in the first node is at a voltage level of the second operating voltage at a time the first voltage is supplied from the multiplexer and transitions to a voltage level of the first operating voltage thereafter.
