Abstract: Described are mechanisms and methods for amortizing the cost of address decode, row-decode and wordline firing across multiple read accesses (instead of just on one read access). Some or all memory locations that share a wordline (WL) may be read, by walking through column multiplexor addresses (instead of just reading out one column multiplexor address per WL fire or memory access). The mechanisms and methods disclosed herein may advantageously enable N distinct memory words to be read out if the array uses an N-to-1 column multiplexor. Since memories such as embedded DRAMs (eDRAMs) may undergo a destructive read, for a given WL fire, a design may be disposed to sense N distinct memory words and restore them in order.

Abstract: A processor includes a processing core and a cache controller including a read queue and a separate write queue. The read queue is to buffer read requests of the processing core to a non-volatile memory, last level cache (NVM-LLC), and the write queue is to buffer write requests to the NVM-LLC. The cache controller is to detect whether the write queue is full. The cache controller further prioritizes a first order of sending requests to the NVM-LLC when the write queue contains an empty slot, the first order specifying a first pattern of sending the read requests before the write requests, and prioritizes a second order of sending requests to the NVM-LLC in response to a determination that the write queue is full, the second order specifying a second pattern of alternating between sending a write request from the write queue and a read request from the read queue.

Abstract: Embodiments include apparatuses, methods, and systems associated with save-restore circuitry including metal-ferroelectric-metal (MFM) devices. The save-restore circuitry may be coupled to a bit node and/or bit bar node of a pair of cross-coupled inverters to save the state of the bit node and/or bit bar node when an associated circuit block transitions to a sleep state, and restore the state of the bit node and/or bit bar node when the associated circuit block transitions from the sleep state to an active state. The save-restore circuitry may be used in a flip-flop circuit, a register file circuit, and/or another suitable type of circuit. The save-restore circuitry may include a transmission gate coupled between the bit node (or bit bar node) and an internal node, and an MFM device coupled between the internal node and a plate line. Other embodiments may be described and claimed.

Abstract: Methods, systems, articles of manufacture, and apparatus are disclosed to decode zero-value-compression data vectors. An example apparatus includes: a buffer monitor to monitor a buffer for a header including a value indicative of compressed data; a data controller to, when the buffer includes compressed data, determine a first value of a sparse select signal based on (1) a select signal and (2) a first position in a sparsity bitmap, the first value of the sparse select signal corresponding to a processing element that is to process a portion of the compressed data; and a write controller to, when the buffer includes compressed data, determine a second value of a write enable signal based on (1) the select signal and (2) a second position in the sparsity bitmap, the second value of the write enable signal corresponding to the processing element that is to process the portion of the compressed data.

Abstract: Described is an low overhead method and apparatus to reconfigure a pair of buffered interconnect links to operate in one of these three modes—first mode (e.g., bandwidth mode), second mode (e.g., latency mode), and third mode (e.g., energy mode). In bandwidth mode, each link in the pair buffered interconnect links carries a unique signal from source to destination. In latency mode, both links in the pair carry the same signal from source to destination, where one link in the pair is “primary” and other is called the “assist”. Temporal alignment of transitions in this pair of buffered interconnects reduces the effective capacitance of primary, thereby reducing delay or latency. In energy mode, one link in the pair, the primary, alone carries a signal, while the other link in the pair is idle. An idle neighbor on one side reduces energy consumption of the primary.
