  • Publication number: 20140078849
    Abstract: A memory device includes a command decoder and control interface logic. One or more external inputs, such as row and column address strobes, communicate with the command decoder through the control interface logic. A control signal is also in communication with the control interface logic. During operation of a drowsy mode in the memory device, a self-refresh signal causes the control signal to disable the external inputs. With the external inputs disabled, command hazards are reduced when exiting drowsy mode.

  • Patent number: 8386886
    Abstract: Methods, apparatuses and systems are disclosed for preserving, verifying, and correcting data in DRAM device during a power-saving mode. In the power-saving mode, memory cells in the DRAM device may be refreshed using a self-refresh operation. This self-refresh operation may allow bit errors to occur in the DRAM device. However, by employing error correction coding (ECC), embodiments of the present invention may detect and correct these potential errors that may occur in the power-saving mode. Furthermore, a partial ECC check cycle is employed to check and correct a sub-set of the memory cells during a periodic self-refresh process that occurs during the power-saving mode.
