Filed:

Dec 23, 1994

Appl. No.:

8/363379

Inventors:

Walter S. Matthews - Folsom CA

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G11B 1722

US Classification:

395 21

Abstract:

A method for retro-storing analog information in a memory circuit first processes first analog data into first digitized data. The first digitized data are then stored in the memory circuit. Second analog data are then received and processed into second digitized data. If storage of the analog information is now required, the second digitized data are stored with the first digitized data in the memory circuit. If storage is not required, the first digitized data are deleted from the memory circuit and the second digitized data are stored in the memory circuit. An integrated storage circuit for retro-storing and retrieving analog information is also described. The circuit includes a control circuit for controlling a processing circuit to store digitized analog data in a nonvolatile memory in response to a control signal. When the control signal is not asserted, the control circuit controls the digitized analog data to be stored in the buffer circuit in a closed loop manner. When the control signal is asserted, the control circuit controls (1) the digitized analog data received after the control signal is enabled and (2) the digitized analog data already stored in the buffer circuit into the nonvolatile memory.

US Classification:

341 20

Abstract:

An ambidextrous, single hand data management device that has been ergonomically optimized to facilitate multiple key per character input, chording. The device has an arrangement of multiple keys which are so situated that the device can be held in either the left or the right hand, by a large range of hand sizes, and data can be quickly and conveniently input, that is, any combination of keys can be quickly and conveniently actuated with a "Microwriting" chordic type of data input, without a hand strap and without dropping the device. The ergonomic arrangement of keys on the casing allows for the device to remain stationary relative to the palm of the hand while that hand is in a multiplicity of orientations. The device can serve as a primary data input device or as a data storage and retrieval device for things like inventory control, names and addresses or daily schedule reminders or, as a combination of all of these. The device is primarily a mobile data input device that allows access to the entire keyboard of characters without the need to look while data are being input but which provides a visual feedback if desired as to what is being input with an LCD.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04N 100
B41B 161

US Classification:

358296

Abstract:

An electronic copying apparatus provides a touch sensitive area placed under a paper on which an image is produced. Pressure on the touch sensitive area produced in rendering the image on the paper generates signals which are detected by a processor and stored as a series of pixel positions in a non-volatile solid-state memory array such as a flash EEPROM memory array. The image stored in the memory array may be read from the array by a computer and utilized as are other files in a computer.

International Classification:

G06F 1202

US Classification:

711173

Abstract:

A memory management method is provided for a nonvolatile memory having a plurality of blocks each of which can be electrically erased and programmed. A data file to be stored in the nonvolatile memory is received. A number of blocks that are available for data storage are located from the plurality of blocks. The data file is stored in a first block of the number of blocks if the size of the data file is smaller than the total storage space of the first block. The data file is stored in the first block and a second block of the number of blocks if the size of the data file is larger than the total storage space of the first block but smaller than the total storage space of the first and second blocks. Unoccupied space of the first or second block by the data file is not used to store other data files such that no file reallocation operation is needed when the first or second block is to be erased. A data storage system having an erasable and programmable memory and a memory management program is also described.

US Classification:

711165

Abstract:

A nonvolatile memory having a plurality of individually erasable blocks is used to store sectors of a file. A method of overwriting the file includes the step of receiving a frame of data. The logical sector that the frame is to be written to is determined. The logical sector corresponds to a first sector located at a first offset in a first block of the nonvolatile memory. The first block also has an associated first logical block number. The frame of data is written to a second sector. The second sector is located at a second offset in a spare block. The first and second offsets are identical. The logical block number of the spare block is updated to be the same as the first logical block number.
