General Description

The AmZ8160 Error Detection and Correction Unit (EDC) contains the logic necessary to generate 6 check bits on a 16-bit data field according to a modified Hamming Code, and to correct the data word when check bits are supplied.

Operating on data read from memory, the AmZ8160 will correct any single bit error and will detect all double on some triple bit errors.

The AmZ8160 is expandable to operate on 32-bit words (7 ch~ck bits) and 64-bit words (8 check bits).

Overview

AmZ8160 Cascadable 16-Bit Error Detection and Correction Unit ADVANCED DATA DISTINCTIVE CHARACTERISTICS • Modified Hamming Code Detects multiple errors and corrects single bit errors in a parallel data word.

Ideal for use in dynamic memory systems.

• Syndromes provided The AmZ8160 makes available the syndrome bits when an error occurs so the location of memory faults can be logged.

Key Features

  • two diagnostic modes, in which diagnostic data can be forced into portions of the chip to simplify device testing and to execute system diagnostic functions. The product is supplied in a 48 lead hermetic DIP package. SYSTEM.
