VARIABLE RESISTANCE MEMORY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17746247 titled 'VARIABLE RESISTANCE MEMORY DEVICE

Simplified Explanation

The patent application describes a variable resistance memory device that includes a stack of insulating sheets and conductive sheets, with a vertical hole passing through them.

  • The stack includes a bit line and a conductive pattern connected to the bit line, both extending vertically in the hole.
  • A resistance varying layer is present between the conductive pattern and the inner side surface of the stack.
  • The resistance varying layer consists of a first carbon nanotube connected to the conductive sheets and a second carbon nanotube connected to the conductive pattern.

Potential applications of this technology:

  • Memory devices: The variable resistance memory device described in the patent application can be used in various memory applications, such as non-volatile memory or random access memory.
  • Data storage: The device's ability to vary resistance allows for efficient data storage and retrieval, making it suitable for use in solid-state drives or other data storage systems.
  • Computing systems: The memory device can be integrated into computing systems, improving their performance and efficiency.

Problems solved by this technology:

  • Memory density: The use of a vertical hole and a stack of insulating and conductive sheets allows for increased memory density, enabling more data to be stored in a smaller space.
  • Resistance variation: The presence of the resistance varying layer, consisting of carbon nanotubes, enables precise control of resistance levels, leading to reliable and efficient data storage.

Benefits of this technology:

  • Increased storage capacity: The variable resistance memory device offers higher memory density, allowing for larger amounts of data to be stored in a compact form.
  • Faster data access: The device's ability to vary resistance enables faster data access and retrieval, improving overall system performance.
  • Energy efficiency: The use of carbon nanotubes in the resistance varying layer contributes to energy efficiency, reducing power consumption in memory devices.
