Lifecycle

The manufacturer’s product page lists this ordering code as obsolete (checked 2026-10-19); that status is reported from the product page and is not a value carried in the data sheet itself. No formal PCN/EOL document was available to cite here, so the lifecycle field is left blank rather than asserted, and the discontinuation is tracked for follow-up.

Provenance

Every figure above is taken from Micron “8Gb: x4, x8, x16 DDR4 SDRAM” 主文档 8gb-ddr4-sdram.pdf（384 页；/Info=Micron/FrameMaker/Adobe PDF Library 16.0.7＝一手排版链，AGG=NONE） (cover feature list, the DDR4 part-number decode and package table). We link no public datasheet: this copy is the manufacturer’s login-gated file and has not been byte-verified against a publicly hosted copy.
