Abstract
Based on the current productization features of phase-change memory,this paper conducts targeted research on four application scenarios in the SSD controller chip:ROM patch loading,abnormal log saving,power-off data preservation,storage of digital certifi-cates,key update,etc.Storing ROM patches can save the ECO cost of the chip and reduce the production cost.Storing abnormal logs can effectively solve the backup of key information of logs and registers when the CPU is in abnormal state,greatly reducing the difficulty of problem location.The storage of digital certificates with key update functionality ensures that sensitive information remains within the main control chip,enhancing security and reliability.Supporting power-off data preservation greatly reduces the capacity requirement for the backup capacitor and lowers the cost of industrial products,making it possible for consumer-grade SSD to support abnormal power-off data preservation.Based on application requirements,a PCM controller was designed and implemented.Simulation results show that the designed PCM controller functions meet the design expectations.It can be seen that with the continuous improvement of PCM's read-write performance and lifespan,PCM has broad application prospects in solid-state storage and other fields in the future.关键词
