The IDT49C460s are high-speed, low-power, 32-bit Error Detection and Correction Units which generate check bits on a 32-bit data field according to a modified Hamming Code and correct the data word when check bits are supplied. The IDT49C460s are performance-enhanced functional replacements for 32-bit versions of the 2960. When performing a read operation from memory, the IDT49C460s will correct 100% of all single bit errors and will detect all double bit errors and some triple bit errors.
