  • Publication number: 20230260572
    Abstract: The present disclosure provides an electronic circuit, a memory device, and a method for operating an electronic circuit. An electronic circuit comprises a driver circuit configured to provide a drive voltage to a word line of the electronic circuit, a suppression circuit electrically connected to the driver circuit and the word line, and a control circuit electrically connected to the suppression circuit. The suppression circuit is configured to generate a voltage drop in the drive voltage. The control circuit controls the suppression circuit.

  • Patent number: 11495287
    Abstract: A memory unit is controlled by a first word line and a second word line. The memory unit includes a memory cell and a transpose cell. The memory cell stores a weight. The memory cell is controlled by the first word line and includes a local bit line transmitting the weight. The transpose cell is connected to the memory cell and receives the weight via the local bit line. The transpose cell includes an input bit line, an input bit line bar, an output bit line and an output bit line bar. Each of the input bit line and the input bit line bar transmits a multi-bit input value, and the transpose cell is controlled by the second word line to generate a multi-bit output value on each of the output bit line and the output bit line bar according to the multi-bit input value and the weight.

  • Patent number: 10636481
    Abstract: A memory cell for computing-in-memory applications is controlled by a first bit line, a second bit line, a word line and a read word line. The read word line transmits an input value. The memory cell includes a plurality of read-decoupled cells. Each of the read-decoupled cells stores a weight and includes a first read-decoupled transistor and a second read-decoupled transistor. The first read-decoupled transistor has a first transistor width and is controlled by the weight. The second read-decoupled transistor has a second transistor width equal to the first transistor width and generates a read bit line signal according to the input value, the weight and the second transistor width. The second transistor width of the second read-decoupled transistor of one of the read-decoupled cells is two times larger than the second transistor width of the second read-decoupled transistor of another one of the read-decoupled cells.
