Abstract
An electrically programmable and erasable memory includes memory cells connected to word lines and to bit lines arranged in columns. Bit lines selection transistors are driven by bit lines selection signals. Column selection latches each includes a locking element for a column selection signal and a circuit for delivering a gate control signal which depends on the output of the locking element. Each column selection latch delivers, in addition to a gate control signal, a bit lines selection signal. This signal depends on the output of the locking element at least during programming and reading phases of the memory cells.
