US Patent:

6590824, Jul 8, 2003

Filed:

Mar 28, 2002

Appl. No.:

10/112521

Inventors:

Alexander Benedix - München, DE
Reinhard Düregger - Poing, DE
Robert Hermann - Altomünster, DE
Roland Barth - San Jose CA

Assignee:

Infineon Technologies AG - Munich

International Classification:

G11C 700

US Classification:

365222, 36523003, 36523006

Abstract:

A dynamic semiconductor memory and a method for operating such a memory includes memory banks with memory cells disposed in rows, and registers associated with the memory banks for storing an address of an open, activated word line. In the event of an external refresh command, a control device causes, after the refresh operation, the state of the memory banks to be reestablished, in particular, the word line whose address was stored in the register to be reactivated. Such a purely on-chip measure increases the operating speed of the memory.

Abstract:

A temperature sensor is integrated together with an integrated circuit on a chip, the sensor delivering a temperature-dependent measuring signal or at least emitting a signal when the chip temperature falls below a specific prescribed value. For such an eventuality, the chip includes a special circuit device thereon, by which a current flow is generated through a provided structure of electrical conductors that keeps the temperature of the integrated circuit above a prescribed minimum temperature.
