摘要： In general, the invention is directed to techniques for scheduling resource access within an intermediate network device. For example, as described herein, a device receives packets for a plurality of sessions that include application-layer data for the sessions. The device determines a weight for each of the plurality of sessions and, during periods of resource congestion, selects one or more sessions for additional resource allocation based on the respective weights of the sessions. The device allocates additional memory resources to selected sessions to enable further buffering of application-layer data such that the device may apply the service to multiple sessions concurrently despite the resource congestion.

摘要： A magnetic tunneling junction (MTJ) in an MRAM array is disclosed with a composite free layer having a FL1/FL2/FL3 configuration where FL1 and FL2 are crystalline magnetic layers and FL3 is an amorphous NiFeX layer for improved bit switching performance. FL1 layer is CoFe which affords a high magnetoresistive (MR) ratio when forming an interface with a MgO tunnel barrier. FL2 is Fe to improve switching performance. NiFeX thickness where X is Hf is preferably between 20 to 40 Angstroms to substantially reduce bit line switching current and number of shorted bits. Annealing at 330° C. to 360° C. provides a high MR ratio of 190%. Furthermore, low Hc and Hk are simultaneously achieved with improved bit switching performance and fewer shorts without compromising other MTJ properties such as MR ratio. As a result of high MR ratio and lower bit-to-bit resistance variation, higher reading margin is realized.

摘要： Reading margin is improved in a MTJ designed for MRAM applications by employing a pinned layer with an AP2/Ru/AP1 configuration wherein the AP1 layer is a CoFeB/CoFe composite and by forming a MgO tunnel barrier adjacent to the CoFe AP1 layer by a sequence that involves depositing and oxidizing a first Mg layer with a radical oxidation (ROX) process, depositing and oxidizing a second Mg layer with a ROX method, and depositing a third Mg layer on the oxidized second Mg layer. The third Mg layer becomes oxidized during a subsequent anneal. MTJ performance may be further improved by selecting a composite free layer having a Fe/NiFeHf or CoFe/Fe/NiFeHf configuration where the NiFeHf layer adjoins a capping layer in a bottom spin valve configuration. As a result, read margin is optimized simultaneously with improved MR ratio, a reduction in bit line switching current, and a lower number of shorted bits.
