摘要： A method of operating a volatile memory device includes storing address information of weak cell rows. According to some examples, after writing to a weak cell row, a refresh operation is performed on the weak cell row within a predetermined time. According to some examples, the writing operation to a weak cell row may be performed with a longer write recovery time than a write recovery time to normal cell rows.

摘要： A semiconductor memory device utilizing a data coding method in an initial operation. The device includes a plurality of counters that count the number of data bits and flag information data bits. A data coding unit selectively applies a first and second operation mode. The first operation mode codes the data of the first through nth data groups such that the counted number of data bits in a first logic state is minimized. The second operation mode codes the data of the first through nth data groups such that the difference between the number of data bits and flag information bits in the first and second logic state are minimized. This prevents the initial logic state of data from being changed due to a voltage drop in the initial operation of the device.

摘要： An image storing and/or replaying apparatus and a method therefor capable of storing a transient image and replaying the stored image at a desired time, the apparatus receives a broadcast stream including a plurality of still image frames and replays the images on a screen. The apparatus includes an image unit, which extracts and stores at least a portion of the plurality of the still image frames and replays the stored still image frames; and a control unit, which controls the extracting, storing, and replaying operations. The apparatus can be adapted to digital and analog broadcasts. In addition, in case of the digital broadcast, an I-frame may be extracted from a compressed image frame and stored. In particular, only some portion of the I-frame, that is, a lower slice of the I-frame, may be stored.
