A computer memory system includes an electro-optical chip, an electrical fanout chip electrically connected to an electrical interface of the electro-optical chip, and at least one dual in-line memory module (DIMM) slot electrically connected to the electrical fanout chip. A photonic interface of the electro-optical chip is optically connected to an optical link. The electro-optical chip includes at least one optical macro that converts outgoing electrical data signals into outgoing optical data signals for transmission through the optical link. The optical macro also converts incoming optical data signals from the optical link into incoming electrical data signals and transmits the incoming electrical data signals to the electrical fanout chip. The electrical fanout chip directs bi-directional electrical data communication between the electro-optical chip and a dynamic random access memory (DRAM) DIMM corresponding to the at least one DIMM slot.

A memory device may determine cell count information from a threshold voltage distribution of memory cells and may determine a detection case based on the cell count information when an error in read data, received from the memory device performing a read operation is not corrected. A memory controller may control the memory device to execute a read operation using a development time determined in consideration of an offset voltage of a read voltage corresponding to the detection case. When an error in the read data is successfully corrected, the memory controller may update a table, stored in the memory controller, using a dynamic offset voltage obtained by inputting the cell count information to a machine learning model.

One embodiment provides an optical encoder. The optical encoder includes an optical comb source to generate a multi-wavelength optical signal; a number of optical filters sequentially coupled to the optical comb source, with a respective optical filter being tunable to pass or block a particular wavelength of the multi-wavelength optical signal based on a corresponding bit value of a multi-bit search word; and a common output for the optical filters to output the filtered multi-wavelength optical signal, which encodes the multi-bit search word and can be used as an optical search signal for searching an optical content-addressable memory (CAM).
