摘要:
A sense amplifier (100) having compensation circuitry is described. The compensation circuitry includes at least one pair of compensation transistors (P01, P02). When compensation is desired, one or a combination of the bulk of the at least one pair of compensation transistors (P01, P02) is provided with one or a combination of compensation voltages. A BIST is carried out for a plurality of sense amplifiers (100) which are grouped and re-offset according to the results of the BIST.

Embodiments of the invention are generally directed to systems, methods, and apparatuses for hybrid memory. In one embodiment, a hybrid memory may include a package substrate. The hybrid memory may also include a hybrid memory buffer chip attached to the first side of the package substrate. High speed input/output (HSIO) logic supporting a HSIO interface with a processor. The hybrid memory also includes packet processing logic to support a packet processing protocol on the HSIO interface. Additionally, the hybrid memory also has one or more memory tiles that are vertically stacked on the hybrid memory buffer.

A method and apparatus are provided for automatically generating the design of a BIST for embedded memories (117) of an IC. The approach relies on counters or pseudo-random generators for the implementation of many of the functions. The invention incorporates soft ware that generates equations (114) that can be used as inputs to a logic synthesis tool (116). The output of the synthesis tool feeds an automatic routing tool where it is merged with the output of the synthesis of the other portions of the integrated circuit, IC. The routing tool places and routes the signals through the logic described by the synthesis tool along with the remainder of the IC. The result is a completed IC design that includes efficient memory BIST circuitry.
摘要:
Während des Funktionstests einer integrierten Schaltung (2) ist diese mit einem Testautomaten (1) verbunden. Ein ausschließlich nur zur Zuführung einer zusätzlichen Versorgungsspannung (VTEST) vorgesehenes Anschlußpad (36) ist mit einem Versorgungsspannungsanschluß (26) des Testautomaten (1) verbunden. Ein im Testbetrieb schaltbarer Schalter (38) verbindet das Anschlußpad (36) zur Ansteuerung irreversibel programmierbarer Schalter (42, 43). Dadurch wird der Aufwand zur Zuführung einer Programmierspannung für die Schaltelemente (42, 43) gering gehalten.

To reduce cost of defect redundancy and trimming in a semiconductor integrated circuit having multiple layer wirings and copper wirings, address for salvaging defect of a memory cell array in a semiconductor is stored by using a nonvolatile memory element constituting a floating electrode by a first layer of polysilicon, or the nonvolatile memory element is programmed in testing the semiconductor integrated circuit, thereby, a special process is not needed in forming the nonvolatile memory element, that is, the nonvolatile memory element can be formed in a process of forming CMOS device and apparatus of laser beam for programming is not needed since the programming is carried out in testing, time necessary for programming can be shortened and therefore, testing cost can be reduced.

A multi-functional general purpose random access memory is fabricated on a single semiconductor substrate. The substrate includes a memory array including a plurality of pages, at least one processing element, and internal-external address mapping means. The pages, processing element, and mapping means are connected to each other by clock, control, data, and address signal lines. The signal lines connect the at least one processing element and the internal-external mapping means to a host processor via an external access path, and signal lines connect the at least one processing element and the memory pages via a multi-function access path, and the signal lines connect the internal-external mapping means to the memory pages via in internal access path.
