Integrated memory having redundant units of memory cells and method for testing an integrated memory
Patent number: 7181579Abstract: An integrated memory has individually addressable normal and redundant units of memory cells. A memory unit is used to store, in a normal mode, an address for one of the normal units which needs to be replaced by one of the redundant units. A comparison unit compares an address which is present on an address bus with an address stored in the memory unit and activates one of the redundant units in the event of a match being identified. The memory also has a test circuit which can be activated by a test mode signal, can reset the memory unit to an initial state, and can store an address for one of the redundant units in the memory unit for subsequently writing an identification code to this redundant unit.Type: GrantFiled: March 12, 2004Date of Patent: February 20, 2007Assignee: Infineon Technologies AGInventors: Aurel von Campenhausen, Manfred Pröll, Jörg Kliewer, Stephan Schröder -
Patent number: 7102912Abstract: An integrated semiconductor memory device includes a memory cell array (B1) with a first bit line and a second bit line (BL, /BL), a controllable resistor (SW) and a control unit (100) configured to control the controllable resistor. In a first operating state of the integrated semiconductor memory device, the first and second bit lines are connected to one another via a first controllable switch (ET1) and also via the controllable resistor (SW) which has been set to a low resistance, to a connection (A10) that applies a mid-voltage (VBLEQ), where the voltage level of the mid-voltage is in the form of an arithmetic mean between a first and second voltage potential (VBLH, VBLL). By virtue of the control unit briefly setting the controllable resistor to a very low resistance in the first operating state of the integrated semiconductor memory device, the period of time required for the first and second bit lines require to assume the mid-voltage (VBLEQ) is shortened.Type: GrantFiled: March 4, 2005Date of Patent: September 5, 2006Assignee: Infineon Technologies, AGInventors: Herbert Benzinger, Jörg Kliewer, Manfred Pröll, Stephan Schröder

Publication number: 20060193168Abstract: An integrated semiconductor memory device includes memory cells each with a selection transistor and a storage capacitor. Memory cells of this type are usually read by the potential of the bit line to which the memory cell is connected being compared in a sense amplifier with the potential of a complementary, second bit line and a voltage difference identified being amplified. The semiconductor memory according to the invention provides for that capacitor electrode which is not connected to the selection transistor to be connected to the complementary, second bit line. As a result, for an operating voltage with the same magnitude, larger quantities of charge can be stored in the storage capacitor since now the two mutually spread potentials output by the sense amplifier are used for biasing the storage capacitor.Type: ApplicationFiled: January 13, 2006Publication date: August 31, 2006Inventors: Stephan Schroder, Herbert Benzinger, Georg Eggers, Manfred Proll, Jorg Kliewer

Patent number: 7085185Abstract: A circuit for controlling an access to an integrated memory includes a command decoder for receiving at least one external command for an access to the memory. An access controller is connected to the command decoder for receiving internal command signals, which are output by the command decoder.

Patent number: 7058851Abstract: A method for repairing an integrated memory having first units of memory cells and second, redundant units of memory cells for replacing first units of memory cells. The first units of memory cells are tested with regard to their functionality. In the case of a defect ascertained in one of the first units, a number of redundant units is programmed as an associated cluster for replacing one or more of the first units. In this way, a repair element is formed with a cluster size corresponding to the number of redundant units. The cluster size of respective repair elements is set in a variable manner by a redundancy circuit. As a result, in a test and repair operation, a comparatively short test time of the memory is made possible in conjunction with a yield that remains good.Type: GrantFiled: November 25, 2002Date of Patent: June 6, 2006Assignee: Infineon Technologies AGInventors: Stephan Schröder, Wolfgang Helfer, Arndt Gruber
