摘要： A Static Random Access Memory (SRAM) having a split write control is described. The SRAM includes bit, write, and write-word lines. Each memory cell within the SRAM includes a delay which is coupled to a dedicated write-word line. When a cell is not being written, its delay receives a delay signal on its associated write-word line, which increases the response time of the cell. When a cell is to be written, however, its delay receives a bypass signal on its associated write-word line, which decreases the response time of the SRAM cell.

摘要： A hardening system includes a data storage device having a data input, a clock input, a data node Q, and a data complement node QN. The data storage device provides drive to the data node Q and the data complement node QN. A hardening circuit includes first, second, third, fourth, and fifth transistor circuits. The first and second transistor circuits form a first node therebetween, and the first transistor circuit prevents the data node Q from changing states in the presence of radiation. The third and fourth transistor circuits form a second node therebetween, and the third transistor circuit prevents the data complement node QN from changing states in the presence of radiation. The first node is coupled to the third transistor circuit, and the second node is coupled to the first transistor circuit. The fifth transistor circuit prevents the first and second nodes from floating.

摘要： A system for initializing circuitry is presented. The system employs a power-on reset circuit having a threshold voltage and a programmable switch circuit. The power-on reset circuit has a detector circuit for detecting a reference voltage, and a one-sided latch for generating an output voltage reflective of the reference voltage. The detector circuit has a threshold after which the one-sided latch is activated. The programmable switch circuit receives the output voltage of the power-on reset circuit and generates an enable signal and its complement based on the status of an internal fuse. The switch point of the power-on reset circuit provides for a rapid increase in output voltage that offsets parasitic leakage current in the programmable switch circuit that can result in improper enable signal output. A high resistance direct path to ground on an output node of the power-on reset circuit prevents residual charge from causing an undesired misfire.
