Data degradation

Data degradation is the gradual corruption of computer data due to an accumulation of non-critical failures in a data storage device. It is also referred to as data decay, data rot, digital decay, or

Error correction code memory is a type of computer data storage that uses an error correction code to detect and correct n-bit data corruption which occurs in memory.

…altering program code or stored data. DRAM may be altered by cosmic rays or other high-energy particles. Such data degradation is known as a soft error. ECC memory can be used to mitigate this type of data degradation. Data degradation results from the gradual decay of storage media over the course of years or…
ECC DIMMs typically have nine memory chips on each side, one more than usually found on non-ECC DIMMs (some modules may have 5 or 18).

In 1982 this 512 KB memory board from Cromemco used 22 bits of storage per 16-bit word to perform single-bit error correction.
