Using phase change memory (PCM) as main memory for embedded systems, such as Beidou navigation terminals, has many advantages, such as non-volatile, energy saving, anti-crack and so on. However, the problem of write operations needs to be solved to prevent premature failure of the PCM chips. In this paper, the data allocation problem of a hybrid PCM and DRAM main memory in Beidou navigation terminals...
Non-volatile memories are good candidates for DRAM replacement as main memory in embedded systems and they have many desirable characteristics. Nevertheless, the disadvantages of non-volatile memory co-exist with its advantages. First, the lifetime of some of the non-volatile memories is limited by the number of erase operations. Second, read and write operations have asymmetric speed or power consumption...
