SYSTEM AND METHOD FOR ERROR PROTECTION OF A MEMORY

摘要

The present invention proposes a system for error protection for a memory during accessing the memory. The system comprises a memory (200) and a DMA-controller (110). The memory (200) comprises a first portion (210) and a second portion (220), wherein the first portion (210) provides address information about the second portion (220) and the second portion (220) is to store data to be accessed. The DMA-controller (110) is adapted to access the second portion (220), or the first portion (210) of the memory (200) by using information stored in the first portion (210) of the memory (200). The DMA-controller (110) includes a checking unit (140) receiving address information from the first portion (210) and determining an address of the memory location in the second portion (220) or in the first portion (210). The checking unit (140) verifies the consistency of the determined address based on the address information.
