摘要： The present disclosure provides methods and circuits for managing failing sectors in a non-volatile memory. A record address and a read control signal are received, where the record address identifies a location in the non-volatile memory. The record address is compared with a plurality of dead sector addresses, where the dead sector addresses correspond to a subset of sectors located in the non-volatile memory. Data located at the record address is determined to be invalid in response to a combination of a first detection that the record address matches one of the dead sector addresses and a second detection that the read control signal indicates a read operation is requested to be performed on the non-volatile memory.

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： Methods and systems are disclosed for code protection in non-volatile memory (NVM) systems. Information stored within NVM memory sectors, such as boot code or other code blocks, is protected using lockout codes and lockout keys written in program-once memory areas within the NVM systems. Further, lockout codes can be combined into a merged lockout code that can be stored in a merged protection register. The merged protection register is used to control write access to protected memory sectors. Lockout code/key pairs are written to the program-once area when a memory sector is protected. The program-once area, which stores the lockout code/key pairs, is not readable by external users. Once protected, a memory sector can not be updated without the lockout code/key pair.

摘要： 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.

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.
摘要翻译： 在非易失性存储器处存储信息的方法包括在擦除存储器上的扇区之前将第一状态位存储在存储器的扇区头部。 擦除扇区后存储第二个状态位。 由于扇区的擦除与状态位的存储交错，所以在擦除记录期间的掉电或其他破坏事件可能导致存储第二状态位的故障。 因此，可以比较第一和第二状态位以确定数据是否在非易失性存储器处被正确擦除。 此外，可以采用多个状态位来指示其他存储器扇区的状态，使得特定扇区的状态位的差异可以指示掉电或其他破坏事件。

摘要： A semiconductor memory device comprises a volatile memory and a non-volatile memory including a plurality of sectors. Each of the plurality of sectors configured to store a sector status indicator and a plurality of data records. A control module is coupled to the non-volatile memory and the volatile memory. The control module manages the sectors by scanning the sectors to identify the records with invalid data; changing the status indicator of a particular sector when all of the records in the particular sector are invalid, and discontinuing scanning the particular sector while all of the records in the particular sector are invalid.

摘要： A system includes an emulation memory having a first sector of non-volatile memory for storing information, in which the non-volatile memory includes a plurality of records. It is determined if a last record written of the plurality of records is a compromised record, if the last record written is not a compromised record, a next write is performed to a record of the plurality of records that is next to the last record written. If the last record written is a comprised record, an address of the compromised record is determined, valid data for the address of the compromised record is written into the record of the plurality of records that is next to the compromised record, and data is written into a record that is next to the record of the plurality of records that is next to the compromised record.
