摘要： A method and apparatus are provided for publishing part datasheets. A part characterization database is created, and the technical characteristics of parts in the database are ascertained. In addition to parts, part groups are created based on common technical characteristics of parts, and a database tree is created based on the technical characteristics of parts and part groups. A publishing interface coupled to the part characterization database is provided for coupling a publishing tool to the part characterization database so as to provide context to the technical characteristics of one or more parts characterized within the part characterization database. A computer program product also is provided for publishing part datasheets. The computer program product comprises means for creating the part characterization database, means for ascertaining the technical characteristics of parts in the database and means for creating part groups based on common technical characteristics of parts. The computer readable medium also comprises means for creating a database tree based on the technical characteristics of parts and part groups and means for providing a publishing interface for coupling a publishing tool to the part characterization database so as to provide context to the technical characteristics of one or more parts characterized within the part characterization database.

摘要： This is a circuit and protocol for relaxing the strobe to data relationship to permit the writing into and reading out of a double data rate DRAM array at data transfer rates higher than any known circuits that utilize a strobe and data protocol. This result is accomplished by modifying the prior art write circuitry by adding a strobe generator coupled to both the data input and the strobe input to control the write circuit multi-latch and by modifying the prior art read circuit by coupling the initial and enable circuit to the data drivers and adding a data compare circuit that is coupled between the memory storage array and the strobe toggle to control the strobe. In this way the present invention relaxes the use of the strobe to data relationships for reads and writes except when there are no data transitions and ends the necessity of aligning the strobe with the data eye. By so eliminating the need for strobe to data eye alignment the present invention can use smaller data eyes and data transfer rates higher than those that can be utilized by the prior art circuits.

摘要： A cached synchronous dynamic random access memory (cached SDRAM) device having a multi-bank architecture and a programmable caching policy includes a synchronous dynamic random access memory (SDRAM) bank, a synchronous static randomly addressable row register, a select logic gating circuit, and mode register for programming of the cached SDRAM to operate in a Write Transfer mode corresponding to a Normal Operation mode of a standard SDRAM during a Write cycle, and to operate in a No Write Transfer mode according to an alternate operation mode during a Write cycle, thereby operating under a first and a second caching policy, respectively. The SDRAM includes a row decoder for selecting a row of data in a memory bank array, sense amplifiers for latching the row of data selected by the row decoder, and a synchronous column selector for selecting a desired column of the row of data. The row register stores a row of data latched by the sense amplifiers and the select logic gating circuit, disposed between the sense amplifiers and the row register, selectively gates the row of data present on the bit lines to the row register in accordance to particular synchronous memory operations being performed.
