Yup. At some point when I wasn't looking, the "-way" in "n-way cache" got promoted from a partial adjective along the lines of "all cars must halt at the four-way stop sign" to a full-blooded noun and term of art. I bumped into it while proofreading a Ph.D. thesis[1]. To help familiarize practitioners with the new cloak of terminology draped over this hoary descendant of Old English "weg", I suggest adding a parenthetical: Geometry of the L1 data cache; that is, line size and number of ways (e.g., \(lq4-way associative\(rq).
