Abstract
PURPOSE:To attain high-sensitivity and high-speed amplification by charging/ discharging directly a bit line from a sense amplifier terminal after the initial amplification of the sense operation is applied via a charge transfer preamplifier and a capacitor. CONSTITUTION:When a memory cell 2a storing '1' is selected, the potential of a bit line 1a precharged to 1/2VCC is increased slightly more than that of the bit line 1b and the level of a node N9 rises slightly higher than that of a node N8 via a capacitor C6 of a charge transfer preamplifier PA. Thus, a transistor (TR) Q18 is turned on and a TR Q17 is turned off and the charge of a node N5 is transferred to the bit line 1b. Then a potential difference amplified correspondingly to a potential difference the bit lines 1a and 1b in nodes N10, N11 is fed directly to a terminal of a sense amplifier SA and the storage content is read. This operation is applied to the storage content 0 similarly and the high-sensitivity and high-speed amplification is applied by using the high-sensitivity charge transfer preamplifier.
