ABSTRACT:
A solid state disc (SSD) Memory comprising the following functional blocks: a memory block (DATA ARRAY) wherein check data bytes are written; a transcoder memory block (SCRAMBLE RAM) which contains the table enabling the reallocation of the data matrix addresses, wherein redundant rows are included; a block (SCRAM DEC) for decoding the addresses of the decoder table; a logic block (FUSE LOGIC) to enable a step to be executed to locate any non-useable row and to substitute said redundant rows therefor; an error correction code (ECC) block for implementing the error correction algorithm; an input buffer block (LOGICAL ROW ADDRESS BUFFER) for storing the row addresses coming from the external bus; a non-volatile memory block, programmed during the test stage and available to a possible processor for handling the contents of the transcoder memory (SCRAMBLE RAM); a word counter block (WORD COUNTER) that is driven from the external clock signal (clock) and counts the number of the addressed words and generates the word addresses; two input and output buffer blocks (DATA IN/OUT) for the data to be written in or read out; a multiplexer block (MUX) by which the data stream is driven to the data memory (DATA ARRAY) or to the transcoder memory (SCRAMBLE RAM).
