  • Publication number: 20240330171
    Abstract: Disclosed is a memory device which includes a plurality of memory chips. Each of the plurality of memory chips includes a plurality of memory banks and a logic circuit. In a first operation mode, the logic circuit writes first data in the plurality of memory banks based on a first command and a first address received from the host, and performs a first processing-in-memory (PIM) operation based on third data received from the host and the first data. In a second operation mode, the logic circuit writes second data in the plurality of memory banks based on the first command and the first address received from the host, and performs a second PIM operation based on fourth data different from the third data received from the host and the second data.

  • Publication number: 20240161850
    Abstract: A memory device which includes a plurality of memory chips. Each of the plurality of memory chips includes a plurality of memory banks and a logic circuit performing a read operation on data stored in the plurality of memory banks based on a first command and a first address received from a host. When a PIM instruction set is stored before the first command and the first address are received, the logic circuit is configured to perform a PIM command execution operation. When an error associated with the PIM command execution operation occurs, the logic circuit is configured to generate error data and record the error data at the log register through the first channels. The logic circuit is configured to output event data indicating an existence of the error data to the host in a first operation mode. The logic circuit is configured to output the error data to the host in a second operation mode.

  • Patent number: 9240290
    Abstract: The present invention is provided with a delay unit for applying a function of a double-pole contact switch and a control function of an activation switch, so as for the contact switch and the activation switch not to operate simultaneously when turned on. Accordingly, when a predetermined time elapses after the double-pole contact switch operates first to prevent an inrush current shock, the activation switch generates a control signal to safely operate an internal circuit such as a central processing device or a control device, so that an electronic product is turned on without an electrical shock or a significant spark. Moreover, if power is cut off by software or the internal circuit is turned off in response to a control signal of the activation switch after an ON button of the electronic product is pressed, the double-pole contact switch is automatically turned off immediately or over a time interval, so that standby power is cut off completely, safely, conveniently, and effectively.
