DEVICES FOR THE SIMULTANEOUS ACTIVATION OF TRAINS OF COMMANDS AND APPLICATIONS TO MEMORIES

摘要

The invention relates to hardware and memory. DCh basic activate devices in a set of N ordered commands circularly h successive therebetween. DCh a device (1) activates h columns (7) of K: SO, SK-1.. DC2 a device (2) activates two line portions (3), (4) among 2L: S'O, S''O .., S'L-1, S''L-1. The DC2 device is slaved to a Cd condition which indicates whether to limit is crossed by activated columns, triggering crossing the passage of the activation, S'i and S''i than S''i and S 'i + 1, or of S''i and S' i + 1 to that of S 'i + 1 and S''i + 1, and so on. Application to the problem of the selection of memory cell groups, in a field organized in matrix, wherein the high address and low are transmitted to DC2 devices (2) and DCh (1) by means of two bus BL (5) and BK (6).
