 The '''MS11 Semiconductor Memory Systems''' were a set of special high-speed memories for the [[PDP-11/45]], which plugged into special dedicated, pre-wired slots in the [[backplane]] of the the [[KB11-A CPU|KB11-A]] and [[KB11-D CPU]].

-The M8110 was later replaced by the M8120, which used the same [[printed circuit board]], but with (as yet un-determined) component variations; the later manuals make it sound as if the bipolar will only work with an M8120, but the early manuals make it clear that an M8110 is acceptable. The -CM and -CP are the nomenclature for the non-parity and parity versions.

 In all versions, each bank included a controller board, and up to 4 storage boards; all cards were [[DEC card form factor|hex]] size. Each bank had to be all MOS or all bipolar (one size); however, there could be one bipolar bank and one MOS bank.
 The storage boards were available in both non-[[parity]] and parity versions (except the larger bipolar ones, which were available in parity only), the latter being indicated by a trailing '-YA' on the board number.
