    Abstract: A memory controller configured to control a memory device including a plurality of banks. The memory controller may determine whether a number of write commands enqueued in a command queue of the memory controller exceeds a reference value, calculate a level of write power to be consumed by the memory device in response to at least some of the write commands from among the enqueued write commands when the number of enqueued write commands exceeds the reference value, and schedule, based on the calculated level of write power, interleaving commands executing an interleaving operation of the memory device, from among the enqueued write commands.

  • Patent number: 10777282
    Abstract: A memory controller to control a memory device includes an Error Checking and Correcting (ECC) engine to perform error detection on data read from the memory device and a data operation manager. The data operation manager is to control a first rewrite operation of the memory device on selected memory cells to compensate for a drift in a distribution of the selected memory cells, based on a result of a test read operation of the memory device on test cells, determine a distribution adjustment degree based on a result of a normal read operation, as an ECC decoding operation corresponding to the normal read operation of the memory device is successfully performed by using the ECC engine, and control a second rewrite operation of the memory device based on the determined distribution adjustment degree.

  • Publication number: 20200254391
    Abstract: A method of predicting membrane fouling in a reverse osmosis process includes collecting information relative to the reverse osmosis process being performed over a predetermined period of time, the collected information including a process factor and a water quality factor, the process factor including a produced water flow rate; calculating a salt removal rate and a pressure drop based on the collected information; normalizing the produced water flow rate, the salt removal rate, and the pressure drop; generating a prediction equation using normalized values of the produced water flow rate, the salt removal rate, and the pressure drop values; and predicting membrane fouling through the generated prediction equation to determine a chemical cleaning time. Process and water quality factors are normalized to temperature and/or flow rate, and the prediction equation uses the normalized factors. Both short-term and long-term predictions are made for chemical cleaning time and membrane module replacement time.
