15 Sep 2011TL;DR: In this article, techniques for encryption key destruction for secure data erasure via an external interface or physical key removal are described, where the eraser provides power and commands to the memory, even when all or any portion of the device is inoperable.
Abstract: Techniques for encryption key destruction for secure data erasure via an external interface or physical key removal are described. Electrical destruction of key material retained in a memory of a storage device renders the device securely erased, even when the device is otherwise inoperable. The memory (e.g. non-volatile, such as flash) stores key material for encrypting/decrypting storage data for the device. An eraser provides power and commands to the memory, even when all or any portion of the device is inoperable. The commands (e.g. erase or write) enable zeroizing or destroying the key material, rendering data encrypted with the destroyed key material inaccessible, and therefore securely erased. Alternatively, the memory is a removable component (e.g. an external security device or smartcard) coupled to the device during storage operation. Removing and physically destroying the memory renders the device securely erased. The device and/or the memory are sealed to enable tamper detection.

TL;DR: In this article, a refresh management table is provided in a flash memory device, and the number of data read and erasure are stored, updated, and managed for each physical block in the management table.
Abstract: In order to provide a flash memory refresh method that efficiently prevents data changing due to a read disturb error as well as prevents data transfer to a host from a temporal interruption, a) a refresh management table is provided in a flash memory device, b) the number of data read and the number of data erasure are stored, updated, and managed for each physical block in the management table, c) a refresh flag is set for a physical block when the number of data read of the physical block has reached a predetermined value, and a refresh is executed according to the flag.

TL;DR: In this article, the problem of preventing data erasure caused by drain disturb even when there is a cell of low drain disturb resistance is solved by changing the corresponding relation of address and word lines through the address change circuit according to change data from the change data memory.
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory device capable of preventing the occurrence of data erasure caused by drain disturb even when there is a cell of low drain disturb resistance. SOLUTION: This device is provided with a change data memory 5 and an address change circuit 6. By changing the corresponding relation of address and word lines through the address change circuit according to change data from the change data memory 5, the word line selection order of an X decoder 2 at the time of write is changed so that an EEPROM cell provided with the memory transistor of low drain disturb resistance is finally written when writing of the data for practical use is performed.

21 Feb 1996TL;DR: In this paper, a key-in data including the character code and the handwritten data including image data are both displayed in an output area 14b on the basis of the real data and its management data.
Abstract: When data is keyed in by operating a keyboard K displayed in a touch panel input area 14a, its character code is stored in a real data memory 46b of a RAM 23 and data on its attribute, pointer and data length is stored as management data. When handwritten data is input by manipulating a handwriting board P displayed in the input area 14a, coordinate data corresponding to the locus of the input handwritten data is stored in the real data memory, and data on its attribute, pointer and data length is stored as management data. The keyed-in data including the character code and the handwritten data including image data are both displayed in an output area 14b on the basis of the real data and its management data. Data edition including data erasure can be dealt with in a unified manner.
