Error detection is done while reading the data from memory. The error detection is performed for data as well as address. For parity memory, only a single-bit error gets detected, whereas in case of ECC memory, along with a single-bit error, a double-bit error also gets detected. These errors are called correctable and uncorrectable errors. The following are characteristics of these errors:
Correctable errors get corrected by the memory controller module and then correct data is given back as read data to the master. It is also written back into the memory to prevent a double-bit error due to another single-bit error at the same memory address.
