Abstract
The present disclosure configures a system component, such as a memory sub-system controller, to control light emitted memory (LEM) devices. The controller receives, from a host, a request to perform one or more memory operations on a set of data. The controller transmits, via one or more optical waveguides, a command to the set of LEM devices to process the set of data based on the one or more memory operations.

A system comprising:
- a set of memory components of a memory sub-system, the set of memory components comprising a set of light emitting memory (LEM) devices, the set of LEM devices comprising light emitting diodes (LEDs), and each LEM device of the set of LEM devices comprising an integrated waveguide configured for light transmission;
- and
- a processing device operatively coupled to the set of memory components via one or more electrical connections and one or more optical waveguides, the one or more optical waveguides being optically coupled to the integrated waveguide of each LEM device to enable optical communication for exchanging data to be read from or stored to the set of LEM devices, the set of LEM devices comprising a first LEM device and a second LEM device, the first LEM device being optically coupled to the second LEM device via the one or more waveguides, the processing device being programmed to perform operations comprising:
- receiving, from a host, a request to perform one or more memory operations on a set of data;
- and
- transmitting, via the one or more optical waveguides, a command to the set of LEM devices to perform the one or more operations on the set of data.
