磁镀线存储器（英语：Plated wire memory）是由贝尔实验室在1957年研发的一个磁芯内存分支。它最主要的优势在于它能够被机械组装，相比手工组装的磁芯，这潜在地降低了成本。

磁镀线存储器使用了网格式导线，并涂上了一层铁-镍合金（透磁合金）薄层，而不是独立的铁酸盐核心。传统存储在铁酸盐核心的磁场被存储在导线本身。磁镀线存储器的工作方式和磁芯存储器基本类似，但是可以和一个不要求重刷新（refreing）的非破坏性读取设备构建在一起。

磁镀线存储器有许多应用，典型的包括航空航天。它在UNIVAC 1110和UNIVAC 9000系列计算机、海盗号登火星计划、LGM-30 Minuteman和哈勃空间望远镜中都有应用。

Plated wire memory is a variation of core memory developed by Bell Laboratories in 1957. Its primary advantage was that it could be machine-assembled, which potentially led to lower prices than the hand-assembled core.

Instead of threading individual ferrite cores on wires, plated wire memory used a grid of wires coated with a thin layer of iron-nickel alloy (called permalloy). The magnetic field normally stored in the ferrite core was instead stored on the wire itself. Operation was generally similar to core, but could also be built with a non-destructive read that did not require refreshing.
