Patricia Arquette, the American actress who won an Oscar in March for her stellar performance in Richard Linklater's coming-of-age drama Boyhood, is to write her memoir. Arquette has signed a book deal with Random House.

The actress, who is currently starring in CSI: Cyber, says she will document her "unconventional family, being a single mother at the age of 20, and her experience as a woman in Hollywood."

In a statement from Random House, Arquette said: "Over the years, the public has come to know aspects of me through my roles in film and television. Writing a memoir will be a new and intimate artistic journey for me, and I hope to bring to it the same honesty I have always sought to bring to my work as an actor."

Arquette made a rousing speech about equality following her Oscars win, telling reporters, "It's time for all the women in America, and all the men that love women and all the gay people and all the people of colour that we've all fought for to fight for us now."

Arquette's memoir becomes even more notable given her high-and-low movie career. She starred in True Romance and Lost Highway and had a lead role in the crime drama Medium, though she's not always found strong roles easy to come by. She married  the actor Nicolas Cage but the couple separated after just nine months.

"Patricia Arquette is a remarkable woman and the instant empathy audiences feel when they see her work on screen is completely evident on the page," said Random House publisher Susan Kamil. "The material I read is revelatory and deeply moving. Not a surprise from an actress of such nuance and intelligence."
