Abstract: Memory devices and systems with automatic background precondition upon powerup, and associated methods, are disclosed herein. In one embodiment, a memory device includes a memory array having a plurality of memory cells and a fuse array configured to store precondition data. The precondition data can identify a portion of the memory array, specify a predetermined precondition state, or a combination thereof. When the memory device powers on, the memory device can be configured to automatically retrieve the precondition data from the fuse array and/or to write memory cells in the portion of the memory array to the predetermined precondition state before executing an access command.

Abstract: Memory devices and systems with automatic background precondition upon powerup, and associated methods, are disclosed herein. In one embodiment, a memory device includes a memory array having a plurality of memory cells at intersections of memory rows and memory columns. The memory device further includes sense amplifiers corresponding to the memory rows. When the memory device powers on, the memory device writes one or more memory cells of the plurality of memory cells to a random data state before executing an access command received from a user, a memory controller, or a host device of the memory device. In some embodiments, to write the one or more memory cells, the memory device fires multiple memory rows at the same time without powering corresponding sense amplifiers such that data stored on memory cells of the multiple memory rows is overwritten and corrupted.

Abstract: A target material delivery system in the form of a nozzle (50) for an EUV radiation source (10). The nozzle (50) includes a target material supply line (66) having an orifice (68) through which droplets (76) of a liquid target material (64) are emitted, where the droplets (76) have a predetermined size, speed and spacing therebetween. The droplets (76) are mixed with a carrier gas (74) in a mixing chamber (54) enclosing the target material chamber (60) and the mixture of the droplets (76) and the carrier gas (74) enter a drift tube (56) from the mixing chamber (54). The droplets (76) are emitted into an accelerator chamber (124) from the drift tube (56) where the speed of the droplets (76) is increased to control the spacing therebetween. A vapor extractor (90) can be mounted to the accelerator chamber (124) or the drift tube (56) to remove the carrier gas (74) and target material vapor, which would otherwise adversely affect the EUV radiation generation.
