Abstract: Apparatuses and methods related to providing coherent memory access. An apparatus for providing coherent memory access can include a memory array, a first processing resource, a first cache line and a second cache line coupled to the memory array, a first cache controller, and a second cache controller. The first cache controller coupled to the first processing resource and to the first cache line can be configured to provide coherent access to data stored in the second cache line and corresponding to a memory address. A second cache controller coupled through an interface to a second processing resource external to the apparatus and coupled to the second cache line can be configured to provide coherent access to the data stored in the first cache line and corresponding to the memory address.

Abstract: Methods, systems, and devices related to sense amplifiers of a memory device serving as a Static Random Access Memory (SRAM) cache. For example, a memory array can be coupled to sense amplifiers. In a first mode, the sense amplifiers can be electrically disconnect from digit lines of the memory array. In the first mode, data and metadata of a cache line can be stored in the sense amplifiers when electrically disconnected from the number of digit lines. In the first mode, a portion of the data can be communicated, based on the metadata, from the sense amplifiers to the processing device. In a second mode, the sense amplifiers can connect to the memory array and sense data from the memory array.

Abstract: A water trap for a gas analyzer includes self-sealing filters formed of a porous polymer that includes a cellulose extract that causes the polymer to become impermeable on contact with water. The water trap in this way automatically protects the gas analyzer from liquid contamination. Preferably, the gas analyzer monitors a pressure parameter of a pneumatic line connected to the water trap and provides an indication that the water trap should be replaced in the event this pressure parameter indicates an abnormal operating condition.
