ATTRIBUTE MEMORY DESCRIPTION AND OPERATION SSD-CXXX(I)-3600 DATA SHEET

ATTRIBUTE MEMORY DESCRIPTION AND OPERATION

The attribute memory plane can be read or written to by asserting the REG# signal, qualified by the appropriate combination of CE1#, OE#, and WE#. An attribute memory map describing the type and location of the information maintained in the attribute memory plane is provided in "Attribute Memory Map" on page 24.

With respect to SiliconDrive CF, attribute memory consists of two sections:

•Card Information Structure (CIS), which contains a description of the Card’s capabilities and specifications.

•Function Configuration Registers (FCRs), which consists of four registers, that can be read or written to by a host to configure the Card for specific purposes.

ATTRIBUTE MEMORY READ OPERATIONS

Attribute memory read operations are enabled by asserting REG#, OE#, and CE1# low. Odd byte read operations from the attribute memory plane are not valid.
