摘要: A method of transferring data from a non-volatile memory (NVM) having a plurality of blocks of an emulated electrically erasable (EEE) memory to a random access memory (RAM) of the EEE includes accessing a plurality of records, a record from each block. A determination is made if any of the data signals of the first data signals are valid and thereby considered valid data signals. If there is only one or none that are valid, the valid data, if any is loaded into RAM and the process continues with subsequent simultaneous accesses. If more than one is valid, then the processes is halted until the RAM is loaded with the valid data, then the method continues with subsequent simultaneous accesses of records.

摘要: 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.

摘要: 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.
