Managing address access information

The invention relates to managing address access information. A device may receive a command for an address of a memory array. Based on or in response to the command, the device may read a first set of flag bits from the memory array. The first set of flag bits may indicate access information for a set of addresses including the address. The device may determine a second set of flag bits based on the command and the address. The second set of flag bits may indicate updated access information for the address. The device may generate a codeword based on the first set of flag bits and the second set of flag bits, and may store the codeword in the memory array. 本申请涉及管理地址存取信息。装置可接收用于存储器阵列的地址的命令。基于或响应于所述命令，所述装置可从所述存储器阵列读取第一组标记位。所述第一组标记位可指示用于包含所述地址的一组地址的存取信息。所述装置可基于所述命令及所述地址确定第二组标记位。所述第二组标记位可指示用于所述地址的更新的存取信息。所述装置可基于所述第一组标记位及所述第二组标记位生成码字，并且可将所述码字存储在所述存储器阵列中。
