Abstract: Memory storage apparatus include a non-volatile memory for storing data and a power management unit configured to sense a level of an external power supply and to predict a loss of the external power supply. A power-polling time control circuit is configured to control a time when a voltage level sourced from the external power supply is reduced below a predetermined level after loss of the external power supply. A control logic controls read and/or write operations of the non-volatile memory responsive to a prediction of loss of the external power supply from the power management unit.

Abstract: A memory system includes a host and an electronic circuit card that can be inserted into the host and electrically connected to the host. If the electronic circuit card is inserted into the host, the host transfers transmission speed information to the electronic circuit card. If transmission speed information received from the host specifies a transmission speed that is identical to a transmission speed of the electronic circuit card, the electronic circuit card transfers a response signal to the host. The host generates a command signal for initializing the electronic circuit card after setting a transmission speed.

Abstract: A method of updating data, which is stored in each page in a non-volatile memory with a multi-plane structure, using an external buffer, is provided. In the method, source data that will not be updated in a page in each plane of the non-volatile memory is moved to the external buffer. The source data is loaded from the external buffer to an empty page in each plane and dummy programming is performed. Update data received from a host is randomly inputted to the page to which the source data has been loaded in each plane and programming is performed.
