INTEGRATED CIRCUIT AND METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18362393 titled 'INTEGRATED CIRCUIT AND METHOD

Simplified Explanation

The patent application describes an interface circuit that includes an integrator circuit and a buffer circuit.

• The integrator circuit is connected to a column of memory cells and receives a signal representing the sum of currents flowing through the memory cells.
• The integrator circuit integrates the signal over time to generate an intermediate voltage.
• The buffer circuit is connected to the output of the integrator circuit and receives the intermediate voltage.
• The buffer circuit is also connected to a row of additional memory cells.
• The buffer circuit generates an analog voltage based on the intermediate voltage.
• The analog voltage is then outputted to the additional memory cells in the row.

Original Abstract Submitted

An interface circuit includes an integrator circuit and a buffer circuit. The integrator circuit is configured to be electrically coupled to a column of memory cells, receive a signal corresponding to a sum of currents flowing through the memory cells of the column, and integrate the signal over time to generate an intermediate voltage. The buffer circuit is electrically coupled to an output of the integrator circuit to receive the intermediate voltage, and is configured to be electrically coupled to a row of further memory cells, generate an analog voltage corresponding to the intermediate voltage, and output the analog voltage to the further memory cells of the row.
