Driver of current-mode type for semiconductor memory has current control with two contacts, driver input contact for data and output contact and two specified current paths, each with switch functioning in relation to driver input signal

摘要

The driver (10) contains current control (12) with the two contacts (16,18), driver input contact (13) for input data and driver output contact (14), dependent on output data. Between driver output contact and first current control contact (16) lies first current path (S1) with first switch (M1) for interruption first current path flow in dependence on driver input data. Second current path (S2) is coupled to first current control contact and contains second switch (M2) for interrupting second current path flow. Both switches safeguard interruption of first or second current path. Independent claims are included for semiconductor memory with invented driver and for operational method of driver.
