Abstract: Disclosed is an analog-to-digital converter including a comparison circuit and a counter circuit. The comparison circuit outputs a comparison result signal based on a pixel signal and a ramp signal and outputs a zero-crossing prediction signal, is the comparison circuit being configured to transition the zero-crossing prediction signal before a zero-crossing time point at which a voltage level of the pixel signal becomes identical to a voltage level of the ramp signal and during a time interval during which the voltage level of the ramp signal is reduced. The counter circuit outputs a low-order bit digital code based on the zero-crossing prediction signal and stops the output of the low-order bit digital code based on the comparison result signal.

Abstract: A memory system includes a memory device including a memory cell array divided into a plurality of memory banks, and a memory controller that sends read requests or write requests to the memory device for the purpose of inputting data to or outputting data from the memory banks of the memory cell array, respectively, and sends the read requests so as to be separated from the write requests based on a read-write switching point. In a first turn, the memory controller sets a near switching point before the read-write switching point. The memory controller blocks scheduling at least one of first bank requests, between the near switching point and the read-write switching point. The memory controller schedules at least one of second bank requests, which cause state switching of the memory banks, so as to be issued between the near switching point and the read-write switching point.

Abstract: The present disclosure relates to an anode electrode active material for a secondary battery containing nickel cobalt molybdenum oxide, an anode electrode for a secondary battery including the same, a secondary battery including the anode electrode for a secondary battery, and a method for manufacturing the same. The novel anode electrode material for a sodium secondary battery containing nickel cobalt molybdenum oxide according to the present disclosure allows intercalation/deintercalation reaction of sodium ion during charge/discharge and does not undergo significant volume change during the intercalation reaction because structure is maintained stably during repeated charge/discharge. As a result, electrode damage and electric short circuit are decreased and, thus, improved electrochemical characteristics can be achieved in long-life and high-rate capability.
