1 Memory CTL Pin Level Functions

2 Pin Level Functions Members –Sirinvas, Karen, Nicco Scope: –Define CTL construct to describe all memory pins that may affect memory test to enable seamless integration of Test Pin Information –Pin Name –Pin Range [L..R] –Direction (Input, Output, InOut) –Logical Port relationship –Polarity (Active High/Low) –Pin Function Data, Address, BistClock, ReadEnable, WriteEnable, ReadWriteEnable, MasterClock, BistEnable, SlaveClock, ScanClock, GroupWriteEnable, GroupReadWriteEnable, (None), Open, OutputEnable, ScanTest, ByPassEnable, MemSelect, ShiftEnable, Active, CAS, RAS, Refresh, ECCDisable, PipelineEnable, [User defined], CAMComparandInput, CAMComparandMask, CAMCompareEnable, CAMMatchOutput, CAMMatch, CAMMultiHit, CAMMatchAddress; ECCEnable, ECCTestInput, ECCDataOutput, ECCOuputEnable,,,,,,,,,,,,, Mile Stone: Draft Document by Feb 2007 (first draft completed in March 2007) Converted to IEEE standard format: May 2007

3 Pin Level Functions Reusing existing Datatypes (21) –MemoryData, MemoryAddress, CoreSelect, OutEnable, MasterClock, MemoryWrite, MemoryRead, ScanMasterClock, ScanSlaveClock, ScanEnable, ScanDataIn, ScanDataOut, In, Out, InOut, Constant, TestData, TestControl, UnusedDuringTest, Row, Column. Can use more than one type to define a pin function

4 Pin Level Functions New types introduced (23) –ScanBypassClock, ColumnAddressSelect, RowAddressSelect, RefreshClock, RefreshClockSelect, ECCEnable, ECCData, ColumnRepairEnable, RowRepairEnable, ColumnRepairData, RowRepairData, TimingMarginSelect, AsyncWriteThrough, GroupWriteEnable, ScanTest, CAMCompareandInput, CAMCompareandMask, CAMCompareEnable, CAMMatchOutput, CAMMatch, CAMMultiHit, CAMMatchAddress, CAMReset. New Keyword in relation block –WriteEnableMap

5 Pin Level Functions New types to be defined –Open, Active, PipelineEnable, ECCOutputEnable,,,,,
