What Are Error Correction Memory Codes?
Error correcting memory codes or we can say error checking and correction memory codes are those codes which allow data being read and transmitted to be tested for errors. It is different from parity checking and controlling because in this errors are not only assessed but also corrected after detection. When data rate increases such error correcting memory codes are specifically designed in the form of data storage and transmitting hardware. Following is the manner in which error correction memory works: When any data unit or any unit is stored in memory RAM or in peripheral storage then calculation is made of the code which describes the sequence of the bit in the word or unit. After this it is stored in the particular unit of data. For every 64 bits unit, an additional amount of 7 bits is needed for storage of this code. When a request is made to the unit for reading it, calculation is repeated by using the constant algorithm for the code in the storage and the about to read unit. T
