  • Patent number: 7501316
    Abstract: Some embodiments provide a memory cell that includes a body region, a source region and a drain region. The body region is doped with charge carriers of a first type, the source region is disposed in the body region and doped with charge carriers of a second type, and the drain region is disposed in the body region and doped with charge carriers of the second type. The body region and the source region form a first junction, the body region and the drain region form a second junction, and 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.

  • Patent number: 7391640
    Abstract: 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.

  • Patent number: 7280425
    Abstract: A one-time programmable (OTP) cell includes an access transistor coupled to an antifuse transistor. Access transistor has a gate oxide thickness that is greater than the gate oxide thickness of the antifuse transistor so that if the antifuse transistor is programmed, the voltage felt across the gate/drain junction of the access transistor is insufficient to cause the gate oxide of the access transistor to break down. The dual gate oxide OTP cell may be used in an array in which only one OTP cell is programmed at a time. The dual gate oxide OTP cell also may be used in an array in which several OTP cells are programmed simultaneously.

  • Patent number: 7246215
    Abstract: A short latency and high bandwidth memory includes a systolic memory that is sub-divided into a plurality of memory arrays, including banks and pipelines that access these banks. Shorter latency and faster performance is achieved with this memory, because each bank is smaller in size and is accessed more rapidly. A high throughput rate is accomplished because of the pipelining. Memory is accessed at the pipeline frequency with the proposed read and write mechanism. Design complexity is reduced because each bank within the memory is the same and repeated. The memory array size is re-configured and organized to fit within desired size and area parameters.
