Description

unit. The chip of the IDT49C465 provides single-error correction and two and It can be expanded to 64-bit widths by cascading 2 units,control. The EDC unit has been designed to be used in either of two configurations in an error correcting memory system.  The bidirectional configuration is most appropriate for systems using bidirectional memory buses. A second system configuration utilizes external octal buffers, and is well suited The IDT49C465 supports partial word writes, pipeliningand error diagnostics.  It also provides parity protection for data on the system side.
