Abstract: Protection of in memory or near memory computations may utilize a controller and an access path that is added through the control path to allow access control on the control path. In some examples, the memory compute request from the host may be intercepted and stopped. In addition, some examples the controller may synchronize the access control policy configuration on data path and control path, express the target address on the data bus instead of the address bus but instead is on the data bus, translate addresses using SWI groups, and the address may be filtered or blocked via the access controller.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of calibrating a component. The method includes receiving previous calibration parameters for an external component at a secondary SoC from a primary SoC, wherein the secondary SoC is coupled to the external component and configured to calibrate the external component. The method further includes determining validity of the previous calibration parameters by the secondary SoC. The method further includes operating the external component by the secondary SoC based on the determined validity of the previous calibration parameters.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of controlling a memory of a computing device by an adaptive memory controller. The method includes collecting usage data from the computing device over a first bin, wherein the first bin is associated with a first weight, wherein the first weight is indicative of one or more of a first partial array self-refresh (PASR) setting a first partial array auto refresh (PAAR) setting and a first deep power down (DPD) setting. The method further includes associating the collected data with a second weight, adapting the first bin based on the second weight, wherein the second weight is indicative of one or more of a second PASR, PAAR, and DPD setting. The method further includes controlling the memory during the next first bin based on the second weight.

Abstract: A memory having a redundancy area is operated in a normal mode and an error is detected. A selecting selects between in-line repair process and off-line repair. In-line repair applies a short term error correction, which remaps a fail address to a remapped memory area of the memory. An in-system repair is applied, for a one-time programmed remapping of the fail address to a redundancy area of the memory. In-system repair utilizes idle time of the memory to maintain valid memory content.
