摘要:
A plurality of semiconductor devices are provided on a carrier for testing or burning-in. The carrier is then cut up to provide single chip-on-carrier components or multi-chip-on-carrier components. The carrier is used as a first level package for each chip. Thus, the carrier serves a dual purpose for test and burn-in and for packaging. A lead reduction mechanism, such as a built-in self-test engine, can be provided on each chip or on the carrier and is connected to contacts of the carrier for the testing and burn-in steps. The final package after cutting includes at least one known good die and may include an array of chips on the carrier, such as a SIMM or a DIMM. The final package can also be a stack of chips each mounted on a separate carrier. The carriers of the stack are connected to each other through a substrate mounted along a side face of the stack that is electrically connected to a line of pads along an edge of each carrier.

A static random access memory (“SRAM”) is provided which includes a plurality of SRAM cells arranged in an array. The array includes a plurality of rows and a plurality of columns. The SRAM includes a plurality of voltage control corresponding to respective ones of the plurality of columns of the array. Each of the plurality of voltage control circuits are coupled to an output of a power supply, each voltage control circuit having a function to temporarily reduce a voltage provided to power supply inputs of a plurality of SRAM cells that belong to a selected column of columns of the SRAM. The selected column is selected and the power supply voltage to that column is reduced during a write operation in which a bit is written to one of the SRAM cells belonging to the selected column.

An integrated redundancy architecture for an embedded memory system whereby a third memory element is added to the redundancy architecture such that all row and column fails may be stored in real-time. Architecture (20) includes a first memory element (22) (FME 22) having a register (24), a second memory element (26) (SME 26) having a register (28), a third memory element (30) (TME 30) having a register (32), and a finite state machine (34) (FSM 34) having a decision algorithm (36). FME (22), SME (26), TME (30), and FSM (34) are electrically connected to a built-in self-test (BIST) module (38). BIST module (38) outputs failed row and column addresses (40), also referred to as “fails,” for rows and columns that are identified as defective during the BIST to the memory elements and FSM (34). FSM (34) allocates redundancy resources of the memory system according to decision algorithm (36).
