Abstract: Methods and systems are provided for decrypting and/or encryption information received by and/or transmitted from an integrated circuit (IC) device input/output (I/O) interface. A decryption circuit is configurable to apply a first decryption algorithm selected from a plurality of decryption algorithms to received information. An encryption circuit is configurable to apply a first encryption algorithm selected from a plurality of encryption algorithms to transmitted information. A key wrapping circuit is configurable to wrap decryption and/or encryption keys associated with the first decryption and/or encryption algorithm. A firewall circuit is configurable to prevent unauthorized access to the wrapped decryption and/or encryption keys. The decryption and/or encryption circuits are reconfigurable to apply a second decryption algorithm and/or a second encryption algorithm to the received information and/or the transmitted information.

Abstract: An integrated circuit includes a buffer circuit, a memory circuit, and a controller circuit that determines if the memory circuit stores information that is valid and determines whether to transmit the information stored in the memory circuit to the buffer circuit based on credits that indicate an amount of storage space available in the buffer circuit. The controller circuit transmits the information to the buffer circuit if the credits indicate that sufficient storage space is available in the buffer circuit to store the information.

Abstract: An apparatus is described. The apparatus includes a memory controller having a network interface and a channel interface. The channel interface is to send read, write and refresh commands into a region of a memory. The network interface is to receive memory access requests from a network, wherein the memory requests target the region of the memory. The memory requests are sent into the network by one or more host interfaces. The memory controller has bank refresh logic circuitry. The memory controller has signaling logic circuitry to send a back pressure signal to the one or more host interfaces. The back pressure signal identifies a bank of the region of the memory that is about to be refreshed by the bank refresh logic circuitry. The back pressure signal is to inform the one or more host interfaces that any memory requests that target the bank will not be serviced by the region of memory before the bank begins to be refreshed.

Abstract: Per channel thermal management techniques are described herein. In one example, a memory controller receives channel temperature information for one or more channels of one or more dies in the stack. The memory controller can then throttle commands at a channel-level based on the channel temperature information. In one example, row commands and column commands to a channel are throttled at independent rates based on the channel temperature information. In one example, a row command throttling rate or column command throttling rate is based on a ratio of alternating on-time to off time of throttling signals, or a window of time in which commands are enabled or disabled to a channel. In one example, the row and column command throttling signals can be staggered across channels or pseudo channels.

Abstract: An integrated circuit may include integrated memory that is formed from a chain of memory blocks. Each memory block may have configurable input and output circuits. The configurable input and output circuits may be interposed between memory circuitry such as a memory array from circuitry external to the memory circuitry. The configurable input and output circuits may have upstream and downstream memory block connection ports. In such a way, configurable input and output circuits in a first memory block may pass control and address signals and data to configurable input and output circuits in a second memory block. By using the configurable input and output circuits, the integrated memory in the integrated circuit may operate to accommodate large bandwidth flows without using the general routing fabric of the integrated circuit.

Abstract: A memory controller circuit includes a first channel circuit having a first programmable switch circuit that is programmable to provide a first request signal indicating a first data access request to a memory circuit. The first programmable switch circuit is programmable to provide a first write data signal indicating first data for storage in the memory circuit. The memory controller circuit includes a second channel circuit having a second programmable switch circuit that is programmable to provide one of the first request signal received from the first programmable switch circuit or a second request signal indicating a second data access request to the memory circuit. The second programmable switch circuit is programmable to provide one of the first write data signal received from the first programmable switch circuit or a second write data signal indicating second data for storage in the memory circuit.
