  • Publication number: 20240021220
    Abstract: Disclosed herein are related to a memory array including a set of memory cells and a set of switches to configure the set of memory cells. In one aspect, each switch is connected between a corresponding local line and a corresponding subset of memory cells. The local clines may be connected to a global line. Local lines may be metal rails, for example, local bit lines or local select lines. A global line may be a metal rail, for example, a global bit line or a global select line. A switch may be enabled or disabled to electrically couple a controller to a selected subset of memory cells through the global line. Accordingly, the set of memory cells can be configured through the global line rather than a number of metal rails to achieve area efficiency.

    Abstract: An error calibration apparatus and method are provided. The method is adapted for calibrating a machine learning (ML) accelerator. The ML accelerator achieves computation by using an analog circuit. An error between an output value of one or more computing layers of a neural network and a corresponding corrected value is determined. The computation of the computing layers is achieved by the analog circuit. A calibration node is generated according to the error. The calibration node is located at the next layer of the computing layers. The calibration node is used to minimize the error. The calibration node is achieved by a digital circuit. Accordingly, error and distortion of the analog circuit could be reduced.
