Promise Me, America is scheduled to come out November 17, according to publisher Little, Brown and Company.
The timing of the book - two weeks after midterm elections in which Democrats seek to regain control of Congress - could raise concerns within his party.
Many Democrats remain divided on Biden's legacy and his ill-fated determination to seek a second term in the White House, and leaders hope to keep the fall campaign focused on the record of Republican President Donald Trump.
"Promise Me, America is about the challenges we faced as a nation. It's about the decisions I made and why I made them," Biden said in a video statement accompanying Wednesday's announcement.
"Most of all, it's about my faith in the promise of America."
Reports of Biden's book have circulated for more than a year, and the former president himself has referred to it during public remarks, appearing to suggest it would be released before November's election.
Little, Brown declined to release financial details for Promise Me, America, although presidents have usually reached deals worth at least seven figures for their memoirs.
Biden - who will turn 84 three days after the publication of Promise Me, America - was sworn into office in the midst of the COVID-19 pandemic and in the aftermath of the January 6, 2021, attack on the US Capitol by Trump supporters seeking to stop his certification as president.
Biden's term was defined by a wide range of conflicts and achievements, from his handling of wars in Ukraine and the Middle East to the passage of ambitious infrastructure and economic aid bills.
But many readers will likely want to know more about his health while president, including the disastrous debate in June 2024 against Trump that led to his giving up his re-election bid.
Then-vice president Kamala Harris, who ran instead, lost decisively to Trump.
