Abstract: An electronic bulk storage having the characteristics of a sequential access storage device. Data are stored parallel by word in a plurality of electronically rotatable memory elements selectable by a memory selection matrix. Each element has a feed-back loop for recirculating data and when selected, a group of elements at an address N is read in parallel a word at a time by electronically rotating data bits stored in the selected memory elements at an address. Controls are provided to select memory elements N+1 whenever elements at address N are selected by the selection matrix. First data is read out of the elements at address N and then data is read out of the elements at address N+1 without any time lost for reselection of memory elements.
