Method and apparatus for supplying regulated power to memory device components |
摘要 |
An internal voltage regulator for a synchronous random access memory ("SDRAM") uses a regulator circuit to supply power to charge pumps that is separate from a regulator circuit that supplies power to the arrays of the SDRAM. The regulator supplies an output voltage to the charge pumps that is maintained constant as the external supply voltage is increased beyond its normal operating range. In contrast, a regulated circuit that supplies power to the arrays increases as the supply voltage is increase beyond its normal operating range. As a result, the voltage regulator allows the arrays to be stress tested with a relatively high regulated output voltage without applying an excessive and potentially damaging regulated output voltage to the charge pumps.
