20100306604 | METHOD AND CIRCUIT FOR BROWNOUT DETECTION IN A MEMORY SYSTEM - Detecting brown-out in a system having a non-volatile memory (NVM) includes loading data in the NVM, wherein a next step in loading is performed on a location in the NVM that is logically sequential to an immediately preceding loading. A pair of adjacent locations include one with possible data and another that is empty. Determining which of the two, if at all, have experienced brownout includes using two different sense references. One has a higher standard for detecting a logic high and the other higher standard for detecting a logic low. Results from using the two different references are compared. If the results are the same for both references, then there is no brownout. If the results are different for either there has been a brownout. The location with the different results is set to an invalid state as the location that has experienced the brownout. | 12-02-2010 |
20110078362 | OPERATING AN EMULATED ELECTRICALLY ERASABLE (EEE) MEMORY - An emulated electrically erasable memory system includes a random access memory (RAM) and a non-volatile memory (NVM). A write access to the RAM is received which provides first write data and a first address, where the first write data is stored in the RAM at the first address, and a currently filling sector of the NVM is updated to store both the first write data and the first address as a first record. In response to the write access, based on whether there are any remaining active records in an oldest filled sector of the NVM, a portion of an erase process or a transfer of up to a predetermined number of active records from the oldest filled sector to the currently filling sector is performed. The predetermined number of active records is less than a maximum number of total records that may be stored within the oldest filled sector. | 03-31-2011 |
20110107009 | NON-VOLATILE MEMORY CONTROLLER DEVICE AND METHOD THEREFOR - A method of storing information at a non-volatile memory includes storing a status bit prior to storing data at the memory. A second status bit is stored after storing of the data. Because the storage of data is interleaved with the storage of the status bits, a brownout or other corrupting event during storage of the data will likely result in a failure to store the second status bit. Therefore, the first and second status bits can be compared to determine if the data was properly stored at the non-volatile memory. | 05-05-2011 |
20110173373 | NON-VOLATILE MEMORY DEVICE AND METHOD THEREFOR - A method of storing information at a non-volatile memory includes storing a first status bit at a sector header of the memory prior to erasing a sector at the memory. A second status bit is stored after erasing of the sector. Because the erasure of the sector is interleaved with the storage of the status bits, a brownout or other corrupting event during erasure of the record will likely result in a failure to store the second status bit. Therefore, the first and second status bits can be compared to determine if the data was properly erased at the non-volatile memory. Further, multiple status bits can be employed to indicate the status of other memory sectors, so that a difference in the status bits for a particular sector can indicate a brownout or other corrupting event. | 07-14-2011 |
20120005403 | RECOVERY SCHEME FOR AN EMULATED MEMORY SYSTEM - In a system having an emulation memory having a first sector of non-volatile memory for storing information, wherein the non-volatile memory includes a plurality of records, a method includes determining if a last record written of the plurality of records is a compromised record; if the last record written is not a compromised record, performing a next write to a record of the plurality of records that is next to the last record written; and if the last record written is a comprised record: determining an address of the compromised record; writing valid data for the address of the compromised record into the record of the plurality of records that is next to the compromised record; and writing data into a record that is next to the record of the plurality of records that is next to the compromised record. | 01-05-2012 |
20120176844 | READ CONDITIONS FOR A NON-VOLATILE MEMORY (NVM) - A method and memory are provided for determining a read reference level for a plurality of non-volatile memory cells. The method includes: performing a program operation of the plurality of non-volatile memory cells; determining a program level of a least programmed memory cell of the plurality of memory cells; performing an erase operation of the plurality of non-volatile memory cells; determining an erase level of a least erased memory cell of the plurality of memory cells; determining an operating window between the program level and the erase level; and setting the read reference level to be a predetermined offset from the erase level if the operating window is determined to compare favorably to a predetermined value. The memory includes registers for storing the program level and the erase level. | 07-12-2012 |
