Abstract
In a memory system, variable resistance circuits, such as transistor circuits, in the word line and bit line decoders are set during bias line set times and/or prior to turn-on times of read operations to increased resistance levels. The variable resistance circuits are kept at the increased resistance levels during an initial turn-on time period during which a selected memory cell may conducts a current spike. The increased resistance levels of the variable resistance circuit may operate to reduce or limit the width of the current spike. In response to the initial turn-on time period ending, the variable resistance circuits are set back to low resistance levels to facilitate subsequent sense results detection events and program operations.
