Speaking to Billboard, Ament revealed that the rockers will begin recording a follow-up to the 2009 release Backspacer in April.
"We did a whole bunch of demos and everybody's got a disc of 25 [songs] right now. April will be the time where we get together and learn to play all these demos and figure out which 12 to 15 of them float to the top. Hopefully we can get something done this year."
The Seattle band released a live album called Live on Ten Legs last January. The live LP featured new cuts of the hits 'Jeremy', 'Alive' and 'Spin The Black Circle'.
Ament explained that his bandmates are anticipating recording new material.
He added: "There's been so much focus on the past that I think all of us are really excited to make a new record and have something to look forward to because we've been digging in the boxes in our basement a lot the last year or so"
Perl Jam celebrated its 20th anniversary last October by performing at a charity concert organised by Neil Young.
The Cameron Crowe-directed Pearl Jam documentary Pearl Jam Twenty will be released later this year.
