Functional Description and Timing Diagrams
Refer to the IBM 64Mb Synchronous DRAM data sheet, document 19L3264.E35855A, for the functional
description and timing diagrams for SDRAM operation.
Refer to the IBM Application Notes: Serial Presence Detect on Memory DIMMsand SDRAM Presence Detect
Definitions for the Serial Presence Detect functional description and timings.
All AC timing information refers to the timings at the SDRAM devices.
