Introduced: July 1974

Full Title

Full titles differ between systems:

IPC:

Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor > using magnetic elements > using single-aperture storage elements, e.g. ring core; using multi-aperture plates in which each individual aperture forms a storage element > using elements with single aperture or magnetic loop for storage, one element per bit, and for destructive read-out > bit-organised, such as 2L/2D-organisation or three-dimensional [3D]-organisation, i.e. for selection of an element by means of at least two coincident partial currents both for reading and for writing

CPC:

Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor (G11C14/00 - G11C21/00 take precedence) > using magnetic elements > using single-aperture storage elements, e.g. ring core; using multi-aperture plates in which each individual aperture forms a storage element > using elements with single aperture or magnetic loop for storage, one element per bit, and for destructive read-out > bit-organised, such as 2L/2D-organisation or three-dimensional [3D]-organisation, i.e. for selection of an element by means of at least two coincident partial currents both for reading and for writing
