摘要： Disclosed is a DRAM circuit that incorporates an improved reference cell, has half the capacitance of the memory cell, does not require a particular reference voltage, and can be formed using the same fabrication processes as the memory cell. This DRAM circuit comprises a memory cell with a single trench capacitor and a reference cell having two trench capacitors. The two reference cell trench capacitors are connected in series through a merged buried capacitor plate such that they provide half the capacitance of the memory cell trench capacitor. Additionally, the reference cell trench capacitors have essentially the same structure as the memory cell trench capacitor so that they can be formed in conjunction with the memory cell trench capacitor. Also disclosed are a design structure for the above-described memory circuit and a method for forming the above-described memory circuit.

摘要： A direct sense memory array architecture and method of operation includes a plurality of memory cells where a bit-line restore voltage level is optimized to reduce memory cell leakage during a first inactive period, and a bit-line preset voltage level is optimized for signal sensing during a second active period. The architecture includes a sense head having of a pair of cross coupled gated inverters. Each of the gated inverters is responsive to a first and second gate control signal which can independently gate a power supply to the inverter circuit within each gated inverter. During the second active period, a first gated inverter senses the data state on the first bit-line, and a second gated inverter performs a preset and write-back function on the first bit-line.

The amplifier stages together form the sense amplifier for the DRAM array. Each amplifier stage includes an isolation capacitor to reduce to a relatively small value any mismatch between the threshold voltages of the transistors within each amplifier stage. A bitline from the DRAM array of memory cells connects to the first amplifier stage. An output from the last amplifier stage connects to a write back switch, the output of which connects to the bitline at the input of the first amplifier stage.
