Method for compressing high repetitivity data, in particular data used in memory device testing

A method for compressing high repetitivity data, in particular data used inmemory device testing, comprising the steps of recognizing a sequence of repetitive data and encoding said sequence of repetitive data, characterized in that the encoding of said sequence of repetitive data is obtained using in combination one or more words with a format for non-compressible data and one or more words with a format for compressible data, a word with a format for non-compressible data being made up of a set of bits, in which a specific bit is set at a first logic value and the remaining bits are formed by at least some of the bits of the non-compressible datum to be encoded, and a word with a format for compressible data being made up of a set of bits, in which a specific bit is set at a second logic value different from said first logic value, a first set of bits indicates the total number of subsequent words, which, together with said word, encode said sequence of repetitive data, and a second set of bits indicates the number of times that the words indicated by said first set of bits are repeated.
