Product Summary
The IDT49C466PQF is a 64-bit Flow-thruEDC. The IDT49C466PQF is a high-speed error detection and correction unit that ensures data integrity in memory systems. The flow-thru architecture, with separate system and memory data buses, is ideally suited for pipelined memory systems. Implementing a modified Hamming code, the IDT49C466PQF corrects all single bit hard and soft errors, and detects all double bit errors. The read/write FIFO can store up to sixteen words. FIFO full and empty flags indicate whether additional data can be written to or read from the EDC.
