发明名称 DEVICE FOR READING A LOW-CONSUMPTION NON-VOLATILE MEMORY AND ITS IMPLEMENTING METHOD
摘要 The reading device enables a non-volatile memory consisting of a matrix of memory cells (TM) to be read. Once the memory cells have been selected to be read in a read cycle controlled by a microprocessor unit, sense amplifiers (4) activated at the start of each cycle supply a binary data word (dx) representing the reading of the selected memory cells. The reading device also comprises time-lag means (3, MF, TF, Cgap) activated at the start of each read cycle. These time-lag means supply a reference signal (rd_mon) that controls the read time of the cells selected independently of the microprocessor unit. This read time is determined so that it is sufficient for reading all the valid data of the selected memory cells in each read cycle. The time-lag means mainly comprise a reference dummy cell (TF) linked to a reference sense amplifier (3), which supplies the reference signal (rd_mon), and a time-lag capacitor (Cgap) linked to the dummy cell.
