Methods, structures, and devices for reducing operational energy in phase change memory

Номер: US20120002465A1
Автор: Roy E. Meade
Принадлежит: Micron Technology Inc

Methods of forming and operating phase change memory devices include adjusting an activation energy barrier between a metastable phase and a stable phase of a phase change material in a memory cell. In some embodiments, the activation energy barrier is adjusted by applying stress to the phase change material in the memory cell. Memory devices include a phase change memory cell and a material, structure, or device for applying stress to the phase change material in the memory cell. In some embodiments, a piezoelectric device may be used to apply stress to the phase change material. In additional embodiments, a material having a thermal expansion coefficient greater than that of the phase change material may be positioned to apply stress to the phase change material.

Быстродействующее графеновое записывающее устройство магниторезистивной памяти

Номер: RU0000179295U1

Полезная модель относится к области спинтроники и компьютерных технологий и предназначена для использования в оперативных запоминающих устройствах. Магниторезистивная оперативная память состоит из двух магнитных слоев (фиксированный и свободный магнитные слои), разделенных тонким диэлектрическим туннельным барьером, и основана на перспективной технологии, в которой для хранения информации используется не электрический заряд, а магнитное состояние вещества. Однако использование внешнего магнитного поля создает технические сложности при конструировании современных устройств памяти. Магниторезистивная оперативная память с переносом спина позволяет решить эти проблемы и создавать ячейки энергонезависимой оперативной памяти с улучшенными характеристиками и на нанометровом масштабе. Для этого, для изменения магнитного состояния свободного слоя в запоминающей ячейке памяти, применяется не внешнее магнитное поле, а перенос спинового момента (spin-transfer torque). И для переноса спинового момента в устройстве используется контакт FM (свободн. магн. слой)/Pt, а генерация спиновых токов осуществляется в контакте графен/Au/SiC. 4 ил.

At least one junction diode fabricated in standard CMOS logic processes can be used as program selectors for the memory cells that can be programmed based on the directions of current flow. These memory cells are MRAM, RRAM, CBRAM, or other memory cells that have a resistive element coupled to the P terminal of the first diode and to the N terminal of a second diode. The diodes can be constructed by P+ and N+ active regions on an N well as the P and N terminals of the diodes. By applying a high voltage to a resistive element and switching the N terminal of the first diode to a low voltage while disabling the second diode, a current flows through the memory cell can change the resistance into one state. Similarly, by applying a low voltage to a resistive element and switching the P terminal of the second diode to a high voltage while disabling the first diode, a current flows through the memory cell can change the resistance into another state. The P+ active region of the diode can be isolated from the N+ active region in an N well by using dummy MOS gate, SBL, or STI isolations.

An apparatus and method of programming a spin-torque magnetoresistive memory array includes a conductive reset line positioned near each of a plurality of magnetoresistive bits and configured to set the plurality of magnetoresistive memory elements to a known state having magnetization perpendicular to the film plane of the magnetoresistive bits by generating a magnetic field when an electrical current flows therethrough. The conductive reset line is positioned such that the magnetic field is applied with a predominant component perpendicular to the film plane when an electrical current of predetermined magnitude, duration, and direction flows through the first conductive reset line. Another conductive reset line may be positioned wherein the magnetic field is created between the two conductive reset lines. A permeable ferromagnetic material may be positioned around a portion of the conductive reset line or lines to focus the magnetic field in the desired direction by positioning edges of permeable ferromagnetic material on opposed sides of the film plane. A spin torque transfer current is applied to selected ones of the magnetoresistive bits to switch the selected bit to a programmed state.

Semiconductor storage device

Номер: US20120081952A1

To write information on a memory cell of SPRAM formed of an MOS transistor and a tunnel magnetoresistive element, the memory cell is supplied with a current in a direction opposite to a direction of a current required for writing the information on the memory cell, and then, the memory cell is supplied with a current required for writing. In this manner, even when the same information is sequentially written on the memory cell, since the currents in the two directions are caused to flow in pairs in the tunnel magnetoresistive element of the memory cell each time information is rewritten, deterioration of a film that forms the tunnel magnetoresistive element can be suppressed. Therefore, reliability of the SPRAM can be improved.

Sensing for nand memory based on word line position

Номер: US20120081964A1
Автор: Haibo Li
Принадлежит: SanDisk Technologies LLC

In a NAND non-volatile memory system, a sensing process accounts for a relative position of a selected non-volatile storage element in a NAND string. In one approach, the storage elements are assigned to groups based on their position, and each group receives a common sensing adjustment during a verify or read process. A group which is closest to a source side of the NAND string may be the largest of all the groups, having at least twice as many storage elements as the other groups. The adjusting can include adjusting a sensing parameter such as body bias, source voltage, sensing time or sensing pre-charge level, based on the position of the sensed storage element or its associated word line position. The adjusting of the sensing may also be based on the control gate voltage and the associated data state involved in a specific sensing operation.
