Toshiba will begin selling 2GB Flash memory chips from April.
The new chips were first made available to Toshiba customers late last year as engineering samples but they will enter commercial production in March and be available from April, said a spokeswoman for Toshiba.
The chips are the highest capacity yet available from any manufacturer and are based on a new production process developed by the Japanese company and its partner Sandisk. The 56-nanometre production process double memory density over the current 70-nanometre process.
The chip will cost ¥3,800 (£15).
