A method for performing a common cancel (CC) function on a dynamic random
access memory (DRAM) semiconductor device to improve reliability and
speed of a memory system. The CC function rakes advantage of the
intrinsic delays associated wit memory read operations at high clock
frequencies, and the increased write latency commensurate with increased
read latencies where non-zero larencies for read and write operations are
the norm by permitting address and command ECC structures to operate in
parallel with the address and command re-drive circuitt The CC function
is extendable to future DDR2 and DDR3 operating requirements in which
latency of higher frequency modes will increase due to the shift from 2
bit pre-fetch to 4 and 8 bit pre-fetch architecture.
