Semiconductor memory component; has current control circuit for output driver and two voltage transmitting buffers

摘要

The control circuit has two voltage transfer devices, formed as buffers (T31,32) from two terminals (P31,P32), reacting to a current control release signal (CCTG). A voltage divider (V31) processes the voltage between the output voltages of the transfer devices and delivers a divided voltage (Vcomp), which is compared with a reference voltage (Vref) by a comparator (C31). Current control counter (D31) generates control bits (ICTR0 to CTR5) to control the current driver (O31) efficiency as a reaction to the comparator output signal. An Independent claim is included for the memory component.
