| 20110038219 | APPARATUS AND METHOD FOR INCREASING DATA LINE NOISE TOLERANCE - Circuits and methods for improving noise tolerance in memories are disclosed such as those that include biasing a data line above a normal threshold voltage, either by providing a higher data line charge voltage with a voltage source, or by providing a higher data line charge voltage with a current source. | 02-17-2011 |
| 20110066816 | NON-VOLATILE MEMORY DEVICE ADAPTED TO IDENTIFY ITSELF AS A BOOT MEMORY - Non-volatile memory devices and methods of their operation are provided. One such non-volatile memory device has an interface and a control circuit. The non-volatile memory device is adapted to identify itself as a boot memory in response to receiving an interrogation request on the interface. | 03-17-2011 |
| 20110069547 | SENSING AGAINST A REFERENCE CELL - Memory devices, bulk storage devices, and methods of operating memory are disclosed, such as those adapted to process and generate analog data signals representative of data values of two or more bits of information. Programming of such memory devices can include programming to a target threshold voltage within a range representative of the desired bit pattern. Reading such memory devices can include generating an analog data signal indicative of a threshold voltage of a target memory cell. The target memory cell can be sensed against a reference cell includes a dummy string of memory cells connected to a target string of memory cells, and, such as by using a differential amplifier to sense a difference between a reference cell and the target cell. This may allow a wider range of voltages to be used for data states. | 03-24-2011 |
| 20110103145 | M+N BIT PROGRAMMING AND M+L BIT READ FOR M BIT MEMORY CELLS - A memory device and programming and/or reading process is described that programs and/or reads the cells in the memory array with higher threshold voltage resolution than required. In programming non-volatile memory cells, this allows a more accurate threshold voltage placement during programming and enables pre-compensation for program disturb, increasing the accuracy of any subsequent read or verify operation on the cell. In reading/sensing memory cells, the increased threshold voltage resolution allows more accurate interpretations of the programmed state of the memory cell and also enables more effective use of probabilistic data encoding techniques such as convolutional code, partial response maximum likelihood (PRML), low-density parity check (LDPC), Turbo, and Trellis modulation encoding and/or decoding, reducing the overall error rate of the memory. | 05-05-2011 |
| 20110116313 | READ METHOD FOR MLC - Memory devices adapted to process and generate analog data signals representative of data values of two or more bits of information facilitate increases in data transfer rates relative to devices processing and generating only binary data signals indicative of individual bits. Programming of such memory devices includes programming to a target threshold voltage range representative of the desired bit pattern. Reading such memory devices includes generating an analog data signal indicative of a threshold voltage of a target memory cell. Cell reads are performed multiple times and the read threshold voltages averaged to more closely approximate actual threshold voltage and to compensate for random noise. | 05-19-2011 |
| 20110128790 | ANALOG SENSING OF MEMORY CELLS IN A SOLID-STATE MEMORY DEVICE - A memory device that includes a sample and hold circuit coupled to a bit line. The sample and hold circuit stores a target threshold voltage for a selected memory cell. The memory cell is programmed and then verified with a ramped read voltage. The read voltage that turns on the memory cell is stored in the sample and hold circuit. The target threshold voltage is compared with the read voltage by a comparator circuit. When the read voltage is at least substantially equal to (i.e., is substantially equal to and/or starts to exceed) the target threshold voltage, the comparator circuit generates an inhibit signal. | 06-02-2011 |
| 20110153922 | NON-VOLATILE MEMORY DEVICE HAVING ASSIGNABLE NETWORK IDENTIFICATION - Memory devices and methods disclosed such as a memory device having a plurality of memory dies where each die includes a network identification that uniquely identifies the memory die on a bus. Access for each memory die to the bus can be scheduled by a bus controller. | 06-23-2011 |
| 20110164449 | PROGRAMMING BASED ON CONTROLLER PERFORMANCE REQUIREMENTS - Methods and solid state drives are disclosed, for example a solid state drive that is adapted to receive and transmit analog data signals representative of bit patterns of three or more levels (such as to facilitate increases in data transfer rates relative to devices communicating data signals indicative of individual bits). Programming of the solid state drive, comprising an array of non-volatile memory cells, might include adjusting the level of each memory cell being programmed in response to a desired performance level of a controller circuit. | 07-07-2011 |
