摘要: A DRAM memory cell uses a single transistor to perform the data storage and switching functions of a conventional cell. The transistor has a floating channel body which stores a potential that corresponds to one of two digital data values. The transistor further includes a gate connected to a first word line, a drain connected to a second word line, and a source connected to a bit line. By setting the word and bit lines to specific voltage states, the channel body stores a digital one potential as a result of impact ionization and a digital zero value as a result of forward bias of body-to-source junction.

摘要: A dynamic random access memory includes a cell having a circuit between a floating-body transistor and a bit line. Activation of the circuit is controlled to provide isolation between the floating body and bit-line voltage both during write operations and during times when the cell is unselected. The added isolation improves performance, for example, by reducing the need for gate-to-body coupling and the magnitude of voltage swings between the bit lines.

摘要: Some embodiments provide a memory cell comprising a body region doped with charge carriers of a first type, a source region disposed in the body region and doped with charge carriers of a second type, and a drain region disposed in the body region and doped with charge carriers of the second type. According to some embodiments, the body region, the source region, and the drain region are oriented in a first direction, the body region and the source region form a first junction, and the body region and the drain region form a second junction. Moreover, a conductivity of the first junction from the body region to the source region in a case that the first junction is unbiased is substantially less than a conductivity of the second junction from the body region to the drain region in a case that the second junction is unbiased. Some embodiments further include a transistor oriented in a second direction, wherein the second direction is not parallel to the first direction.

摘要: A voltage droop detector captures the very high-frequency noise on the power grid of a load, such as a microprocessor. The droop detector includes twin circuits, one of which receives the voltage from the power grid of the load, the other of which receives a filtered voltage. A 0th droop, as well as 1st droops, 2nd droops, and so on, are captured and stored for subsequent analysis. The circuits sample the voltages frequently enough to ensure that all droop events are captured. Other embodiments are described and claimed.
