Pre-decoder for glitch free word line addressing in a memory device

摘要

A reset circuit in a memory device applies a reset to the global X-address latch and the local X-address latch. This resets those latches and effectively de-addresses all word lines prior to application of the next address. This eliminates any overlap of main word line signals between successive addresses thereby eliminating a possible glitch that would cause simultaneous word line addressing and potentially a memory read or write error. By terminating the addressing, the address cycle time may be reduced.
