Abstract
A circuit for activating page-write operations in a floating-gate memory includes a first and a second time lag circuit. A resetting signal resets a first time lag whenever a word is written in a buffer of the memory. The first time lag circuit provides a state bit indicating that the first time lag has ended or not ended. The second time lag circuit activates a second time lag at the end of the first time lag and the end of the second time lag activates the writing of the page in the memory. The invention also relates to a method of writing in memory that uses a first and a second time lag.
