INTEGRATED CIRCUIT STRUCTURE AND FABRICATION THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17689784 titled 'INTEGRATED CIRCUIT STRUCTURE AND FABRICATION THEREOF

Simplified Explanation

The abstract describes an integrated circuit (IC) structure that includes a magnetic tunnel junction (MTJ) cell, a transistor, and two word lines. The transistor is connected to the MTJ cell and has two independent gate terminals. The first word line is connected to the first gate terminal, and the second word line is connected to the second gate terminal. The resistance state of the MTJ cell depends on the voltages applied to the word lines, and it follows either an AND gate logic or an OR gate logic.

  • The IC structure includes an MTJ cell, a transistor, and two word lines.
  • The transistor is connected to the MTJ cell and has two independent gate terminals.
  • The first word line is connected to the first gate terminal, and the second word line is connected to the second gate terminal.
  • The resistance state of the MTJ cell is determined by the voltages applied to the word lines.
  • The resistance state of the MTJ cell follows either an AND gate logic or an OR gate logic.

Potential Applications

  • This IC structure can be used in various electronic devices that require logic operations, such as computers, smartphones, and IoT devices.
  • It can be applied in memory devices, such as non-volatile memory or cache memory, to store and retrieve data efficiently.

Problems Solved

  • The IC structure solves the problem of integrating logic operations with memory cells in a compact and efficient manner.
  • It provides a simplified and versatile approach to perform logic operations using the resistance state of the MTJ cell.

Benefits

  • The IC structure offers a compact and integrated solution for performing logic operations.
  • It reduces the complexity and size of circuitry by combining logic operations with memory cells.

Original Abstract Submitted

An IC structure comprises an MTJ cell, a transistor, a first word line, and a second word line. The transistor is electrically coupled to the MTJ cell. The transistor comprises a first gate terminal and a second gate terminal independent of the first gate terminal. The first word line is electrically coupled to the first gate terminal of the transistor. The second word line is electrically coupled to the second gate terminal of the transistor. A resistance state of the MTJ cell is dependent on a first word line voltage applied to the first word line and a second word line voltage applied to the second word line, and the resistance state of the MTJ cell follows an AND gate logic or an OR gate logic.
