Abstract
Memory devices and systems incorporate on-die termination for signal lines. A memory device comprises an integrated circuit die. The integrated circuit die comprises a pair of input signal pins that supply a pair of input signals, and an on-die termination circuit coupled between the pair of input signal pins that differentially terminates the pair of input signals.
Claims15
A memory apparatus comprising:
- a memory device configured with on-die differential termination of memory device data and strobe lines wherein memory device power draw is reduced comprising:
- an integrated circuit die comprising:
