Compute-in-memory devices and methods for operating the same

A memory circuit, comprising:

• a first memory cell configured to store a first data element accessible through a first access line;
• a second memory cell configured to store a second data element accessible through a second access line, wherein the first access line and the second access line are disposed in a single column, and the first and second memory cells are disposed in a first row and a second row, respectively;
• and
• a first computation element configured to generate a first multiply-accumulate (MAC) value calculated based on the first data element, the second data element, a third data element, and a fourth data element.

A method for operating a memory circuit, comprising:

• simultaneously updating a first memory cell of a memory array with a first data element through a first access line and updating a second memory cell of the memory array with a second data element through a second access line, wherein the first and second access lines are disposed in a single column of the memory array;
• multiplying the first data element by a third data element to generate a first product, and multiplying the second data element by a fourth data element to generate a second product;
• and
• summing the first product and the second product to generate a multiply-accumulate (MAC) value.
