摘要: A memory device includes N memory planes (N is an integer greater than 1), M asynchronous multi-plane independent (AMPI) read units (M is an integer smaller than or equal to N), a first microcontroller unit (MCU), and a multiplexing circuit coupled to the N memory planes, the first MCU, and the M AMPI read units. Each AMPI read unit is configured to provide an AMPI read control signal for a respective memory plane to control an AMPI read operation on the respective memory plane. The first MCU is configured to provide a non-AMPI read control signal for each memory plane to control a non-AMPI read operation on each memory plane. The multiplexing circuit is configured to, in a non-AMPI read operation, direct a non-AMPI read control signal to each memory plane from the first MCU, and in an AMPI read operation, direct each AMPI read control signal of M AMPI read control signals to the respective memory plane from the corresponding AMPI read unit.

摘要: In some examples, command decoders may have multiple command paths. In some examples, command signals from one command path may be provided to another command path from a node located between two latches of the command decoder, such as two latches of a flip-flop. In some examples, the command decoder may include separate flip-flops for different command modes. In some examples, the separate flip-flops may be tristate flip-flops. In some examples, the command decoder may include alternate logic circuits rather than a multiplexer.

摘要: Methods and apparatuses to provide FPGA neighbor output mux direct connections to reduce, and potentially minimize, routing hops are described. Embodiments described herein include the addition of direct connections from one tile to the output muxing of a neighboring tile. An FPGA apparatus includes a plurality of logic block tiles. One or more direct connections extend from one or more logic block tiles of the plurality of logic block tiles to one or more inputs of output multiplexors (muxes) of one or more neighboring logic block tiles. The one or more direct connections are configured to drive one or more wires that start at the one or more neighboring logic block tiles.

摘要: Techniques and mechanisms for determining an amount of skew between two clock signals. In an embodiment, detector circuitry receives a first signal and a signal which indicate (respectively) a NAND combination of clock signals, and a NOR combination of the clock signals. The detector circuitry evaluates a first length of time that the first signal indicates a respective first logic state, and a second length of time that the second signal indicates a respective second logic state. The skew is calculated based on a difference between the first length of time and the second length of time. In another embodiment, one of the first signal or the second signal is generated with a combinatorial logic gate, a transistor of which is relatively large, as compared to another transistor which is to operate based on one of the first signal, the second signal, or the clock signals.

摘要: A semiconductor device includes a ROM, a differential sense amplifier and a multiplexer logic circuit. The ROM has memory cells in rows along word lines and columns along bit lines, and a reference column having reference transistors along a reference bit line. The multiplexer logic circuit couples a selected bit line to a first differential amplifier input and couples the reference bit line to the second differential amplifier input and controls a reference current of the reference bit line to be between a first bit line current of a programmed memory cell and a second bit line current of an unprogrammed memory cell.

摘要: A programmable logic device (PLD) supports scan testing of configurable logical blocks using scannable word line (WL) shift register (WLSR) chains to enable writes to configurable memory bits while scan test data is input via a scan chain comprising scannable bit line (BL) shift registers (BLSRs). Input test data may be shifted onto BLs to write data into a configurable memory bit when a corresponding WL associated with the configurable memory bit is asserted. Logic blocks may comprise: latch-based configurable memory bits, scannable WLSRs forming a distinct WLSR chain in shift mode and driving corresponding WLs. Each WL, when asserted, enables writes to a corresponding configurable memory bit. A scannable BLSR receives serial scan test vector input in shift mode and drives a corresponding BL coupled to the configurable memory bit to write data to the configurable memory bit when the associated WL is asserted.

摘要: A memory system comprises a plurality of memory sub-systems, each with a memory bank and other circuit components. For each of the memory sub-systems, a first buffer receives and stores a read-modify-write request (with a read address, a write address and a first operand), a second operand is read from the memory bank at the location specified by the read address, a combiner circuit combines the first operand with the second operand, an activation circuit transforms the output of the combiner circuit, and the output of the activation circuit is stored in the memory bank at the location specified by the write address. The first operand and the write address may be stored in a second buffer while the second operand is read from the memory bank. Further, the output of the activation circuit may be first stored in the first buffer before being stored in the memory bank.
