20090089536 | METHOD FOR ASSIGNING ADDRESSES TO MEMORY DEVICES - A memory system having a memory controller and several separate memory devices connected to the controller by a system bus. The memory devices each included an array of memory cells, addressing circuitry used to address the cells and an address storage circuit which stores a local address unique to each of the memory devices.

20100020616 | Soft Errors Handling in EEPROM Devices - Soft errors occur during normal use of a solid-state memory such as EEPROM or Flash EEPROM. A soft error results from the programmed threshold voltage of a memory cell being drifted from its originally intended level. The error is initially not readily detected during normal read until the cumulative drift becomes so severe that it develops into a hard error. Data could be lost if enough of these hard errors swamps available error correction codes in the memory. A memory device and techniques therefor are capable of detecting these drifts and substantially maintaining the threshold voltage of each memory cell to its intended level throughout the use of the memory device, thereby resisting the development of soft errors into hard errors. | 01-28-2010 |
20100064098 | Device and Method for Controlling Solid-State Memory System - A memory system includes an array of solid state memory devices which are in communication with and under the control of a controller module via a device bus with very few lines. This forms an integrated-circuit mass storage system which is contemplated to replace a mass storage system such as a disk drive memory in a computer system. Command, address and data information are serialized into component strings and multiplexed before being transferred between the controller module and the array of memory devices. The serialized information are is accompanied by a control signal to help sort out the multiplexed components. Each memory device in the array is mounted on a multi-bit mount and assigned an array address by it an array mount. An A memory device is selected by an appropriate address broadcast over the device bus, without requiring the usual dedicated select signal. A reserved array particular mount multi-bit configuration is used to unconditionally select the device mounted thereon. A reserved predefined address broadcast over the device bus deselects all previously selected memory devices. Read performance is enhanced by a read streaming technique in which while a current chunk of data is being serialized and shifted out of the memory subsystem devices to the controller module, the controller module is also setting up the address for the next chunk of data to begin to address the memory system. | 03-11-2010 |
