Associative memory device with optimized occupation, particularly for the recognition of words

A computer-implemented method for optimizing memory occupation in an associative memory, the method comprising:

• parsing a dataset comprising sequences of analog values representing words to determine a length associated with each word of said dataset;
• collecting sequences of analog values representing a word from said dataset having comparable lengths into groups, the words of each group having a different length than the words of each of the other groups;
• and
• writing said groups of data to a plurality of sections, respectively, of an associative analog memory wherein the writing includes:
• writing the groups of data in memory locations along lines of the memory extending along a first direction, wherein memory locations adjacent in the first direction and belonging to the same line store data belonging to different groups;
• and
• writing the data of the same group in memory locations adjacent in a second direction and belonging to different lines.
