  • Patent number: 8080440
    Abstract: A phase change random access memory PCRAM device is described suitable for use in large-scale integrated circuits. An exemplary memory device has a pipe-shaped first electrode formed from a first electrode layer on a sidewall of a sidewall support structure. A sidewall spacer insulating member is formed from a first oxide layer and a second, “L-shaped,” electrode is formed on the insulating member. An electrical contact is connected to the horizontal portion of the second electrode. A bridge of memory material extends from a top surface of the first electrode to a top surface of the second electrode across a top surface of the sidewall spacer insulating member.

  • Patent number: 7977186
    Abstract: A substrate of a non-volatile storage system includes selected regions in which additional ions are deeply implanted during the fabrication process. NAND strings are formed over the selected regions such that end word lines of the NAND strings are over the deeply implanted ions. The presence of the deeply implanted ions below the end word lines increases a channel capacitance of the substrate under the end word lines. Due to the increased capacitance, boosting of a channel in the substrate below the end word lines is reduced, thereby reducing the occurrence of gate induced drain leakage (GIDL) and band-to-band tunneling (BTBT) and, consequently, program disturb. A shallow ion implantation may also be made to set a threshold voltage of storage elements of the NAND string.

  • Publication number: 20090212323
    Abstract: A silicon-controlled rectifier (SCR) device having a high holding voltage includes a PNP transistor and an NPN transistor, each transistor having both p-type and n-type dopant regions in their respective emitter areas. The device is particularly suited to high voltage applications, as the high holding voltage provides a device which is more resistant to latchup subsequent to an electrostatic discharge event compared to devices having a low holding voltage.
