摘要:
A semiconductor memory maintains securely the stored contents in the memory cells, and it is written with data reliably even in a case where a relatively low supply voltage is applied. A memory cell M00 comprises a pair of inverters cross-coupled with each other, a first switching unit provided between bit line BL and the output terminal of one of the inverters, and a second switching unit provided between bit line XBL and the output terminal of the other inverter. The first switching unit and the second switching unit are controlled to be conductive such that the conductance of the switches be larger for the writing operation than for the reading operation.

It is a flip-chip mounting substrate according to the invention has a wiring pattern in which bonding pads and predetermined parts of lead wires continuously extending from the bonding pads are exposed from an insulating layer or a solder resist. In the flip-chip mounting substrate, exposed parts of the wiring pattern are formed in to a plurality of different shapes. The exposed parts are formed so that the areas of the bonding pads are substantially equal to one another, and that the total areas of predetermined parts of the lead wires continuously extending from the bonding pads are substantially equal to one another.
