Abstract
Examples include techniques to mirror a command/address or interpret command/address logic at a memory device. A memory device located on a dual in-line memory module (DIMM) may include circuitry having logic capable of receiving a command/address signal and mirror a command/address or interpret command/address logic indicated in the command/address signal based on one or more strap pins for the memory device.
Claims30
An apparatus comprising:
- circuitry for a memory device on first side of a dual in-line memory module (DIMM), the circuitry including logic, at least a portion of which comprises hardware, the logic to:
- receive a command/address signal that indicates a first command/address to the target memory device;
- determine based on a strap pin of the memory device that the first command/address indicated in the command/address signal is to be mirrored;
- and
- mirror the first command/address to the memory device such that the first command/address indicated in the command/address signal is a mirror of a second command/address to a memory device on a second side of the DIMM.

A method comprising:
- receiving, by circuitry at a target memory device on first side of a dual in-line memory module (DIMM), a command/address signal indicating a first command/address to the target memory device;
- determining based on a strap pin of the target memory device that the first command/address indicated in the command/address signal is to be mirrored;
- and
- mirroring the first command/address to the target memory device such that the first command/address indicated in the command/address signal is a mirror of a second command/address to a non-target memory device on a second side of the DIMM.

An apparatus comprising:
- circuitry for a memory device on a first side of a dual in line memory module (DIMM), the circuitry including logic, at least a portion of which comprises hardware, the logic to:
- receive a command/address signal;
- determine based on a strap pin of the memory device whether command/address logic indicated by the command/address signal has been inverted;
- and
- interpret the command/address logic indicated by the command/address signal based on the determination.

A method comprising:
- receiving, by circuitry a target memory device on a dual in-line memory module (DIMM), a command/address signal;
- determining based on a strap pin of the memory device whether command/address logic indicated by the command/address signal has been inverted;
- and
- interpreting the command/address logic indicated by the command/address signal based on the determination.
1 more element
A system comprising:
- a dual in-line memory module (DIMM) including one or more first memory devices on a first side and one or more second memory devices on a second side;
- and
- a memory device from among the one or more first memory devices, the memory device having a first strap pin and including logic, at least a portion of which comprises hardware, the logic to:
- receive a first command/address signal that indicates a first command/address targeted to the memory device;
- determine whether the first strap pin is connected to a power pin;
- and
- mirror the first command/address targeted to the memory device based on the determination such that the first command/address indicated in the first command/address signal is a mirror of a second command/address to a memory device from among the one or more second memory devices on the second side of the DIMM.
