The centre-back, 34, made the loan move from Millwall in August and has barely missed a match since as Paolo Di Canio's side have adapted well to League One football.
Ward told the Swindon Advertiser: "It is up to the manager, but I am very happy here and I am pleased with how things have been going, although it is the club's decision.
"All I have been doing is playing and enjoying it, and hopefully that can continue and I can carry on contributing to where the club wants to go.
"It would be very interesting and something I would be keen on, but it is still a little way away and hopefully we can continue to do well."
