From the shop's description

UM6264B-10L 8K X 8 64k STANDARD SRAM 100ns IC DIP-28 Wide The UM6264B-10L is presented as a compact static random-access memory device intended to supply dependable temporary storage inside digital systems. As a static RAM element, it provides straightforward read/write access without refresh cycles and is intended to simplify system timing and memory management for embedded designs. The device is described for use where predictable, low-latency memory operations are needed: it can be connected directly to system buses and processors and is designed for straightforward integration into common board-level memory architectures. Control inputs allow selective enabling and disabling to coordinate with shared bus environments. Built on a mature CMOS process, the UM6264B-10L emphasizes reliable, stable operation in embedded contexts and is offered in standard package styles to fit both prototype and production workflows. The description in the PDF positions the part as a general-purpose SRAM building block for digital designs requiring simple, deterministic volatile storage. Features: Directly TTL-compatible inputs and outputs. Full static operation (no clock or refresh required). Common I/O using three-state outputs for shared-bus systems. Output enable plus two chip-enable inputs for flexible enable/power-down control.
