MEMORY STRUCTURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17815285 titled 'MEMORY STRUCTURE
Simplified Explanation
The abstract describes a memory structure that includes a static random-access memory (SRAM) cell with various transistors and nanostructures stacked vertically. It also includes write bit-line conductors and a write bit-line-bar conductor in a metal layer below the SRAM cell.
- The SRAM cell has multiple transistors, including pull-up (PU) and pull-down (PD) transistors for write ports, pass-gate (PG) transistors for write ports, PD transistors for read ports, and PG transistors for read ports.
- The nanostructures are vertically stacked within the transistors.
- The write bit-line conductor is connected to the source/drain feature of the first write-port pass-gate transistor.
- The write bit-line-bar conductor is connected to the source/drain feature of the second write-port pass-gate transistor.
Potential applications of this technology:
- Memory devices: This memory structure can be used in various memory devices, such as computer RAM, cache memory, and embedded memory in electronic devices.
- Data storage: The SRAM cell can store and retrieve data quickly, making it suitable for applications that require fast access to data, such as real-time processing and high-speed computing.
Problems solved by this technology:
- Data access speed: The SRAM cell's design and structure allow for faster data access compared to other memory technologies like dynamic random-access memory (DRAM).
- Data retention: The SRAM cell can retain data without the need for constant refreshing, ensuring data integrity and reducing power consumption.
Benefits of this technology:
- Faster data processing: The SRAM cell's fast access speed enables quicker data processing, improving overall system performance.
- Lower power consumption: The SRAM cell's ability to retain data without refreshing reduces power consumption, making it energy-efficient.
- Compact design: The vertical stacking of nanostructures and the use of metal layers optimize space utilization, allowing for a more compact memory structure.
