A memory refresh device comprises an ordinary patrol control unit (24) for controlling an ordinary patrol operation in which a memory (11) is patrolled, an additional patrol control unit (25) for, when an error of the memory (11) is detected in the ordinary patrol operation, controlling an additional patrol operation in which an error generating portion in the memory (11) is patrolled, a measuring unit (15) for, when an error is detected in the additional patrol operation, measuring information on the error in the error generating portion as error frequency, and a refresh period adjusting unit (26) for adjusting a refresh period according to the error frequency measured by the measuring unit (15). Thus, the optimization of the refresh period is efficiently performed according to the state of the generation of the error in the memory.

The invention relates to a method for determining a temperature (T) of a plurality of memory elements (10) having a temperature-dependent probability (P) of assuming a particular bit value, the method comprising: triggering (110) the plurality of memory elements (10) to assume the particular bit value; reading out (120) the contents of the plurality of memory elements (10) to obtain read data (D), and processing (130) the read data (D) for determining a value (Vact) indicative of the temperature (T). The invention also relates to a program product comprising instructions for causing a processor to perform the method. Such computer program is advantageously used in a smartcard, which then does not need any structural modification at all. The invention further relates to a system for determining a temperature (T) of a plurality of memory elements (10). Such system is advantageously implemented in an integrated circuit, wherein the plurality of memory elements (10) forms part of an integrated memory. The invention provides that temperature (T) can be determined without the need for a separate temperature sensor. The only real requirement is the presence of a plurality of memory elements (10) having a temperature-dependent probability (P) of assuming particular bit value.

The invention discloses a method for improving the performance of an SSD and an SSD, which is characterized in that the SSD applies to a host for allocating a memory space as a mapping table buffer area, stores the mapping table in the mapping table buffer area, and accesses the mapping table buffer area through a high-speed interface The mapping table entry data. In view of the limitation of the mapping table of Dramless SSD, the random reading and writing of the host will frequently trigger the replacement of the internal mapping table, resulting in the problem of extremely low performance. The HMB strategy of the present invention based on NVMe SSD can be used as a mapping table cache by applying for memory on the host side , so as to avoid frequent loading and refreshing of the mapping table, thereby achieving the purpose of improving the operating performance of the SSD.

The present disclosure discloses a method for preventing repeated updating of an address table in Ethernet ring network protection, including: an Ethernet ring network node sends an Ethernet ring network protection protocol frame and encapsulates its own node information into the Ethernet ring network protection protocol frame; an Ethernet ring network node receives the Ethernet ring network protection protocol frame and matches the node information encapsulated in the received Ethernet ring network protection protocol frame with its own node information; and when the matching is successful, the Ethernet ring network node does not update the address table. The present disclosure further discloses a system for preventing repeated updating of an address table in Ethernet ring network protection. In the system, a matching unit is used for matching the node information encapsulated in the received Ethernet ring network protection protocol frame with the node information of an Ethernet ring network node itself; and when the matching is successful, the Ethernet ring network node does not update the address table. Through the method and system of the disclosure, the problem of repeated updating of an address table in Ethernet ring network protection in the scenario of requesting local protection switching can be solved.

The present invention provides a TPM and TCM universal server chip initialization method, system, BIOS and storage medium, all including: when TPM / TCM is set in the BIOS initialization server, call BMC to read TPM / TCM from TPM / TCM board card Pull-up and pull-down resistor codes are recorded as index codes; according to the above index codes, the pre-established security chip configuration files are coded and indexed to find out the reference values ​​of the relevant configuration information on the working line of the TPM / TCM in the server, which are recorded as pending Configure parameter information; use the found parameter information to be configured to initialize the corresponding parameters in the server ME firmware. The invention is used to increase the convenience of TPM / TCM chip configuration in the initialization server.
