2.1.2System Memory Timing Support

The IMC supports the following DDR3L Speed Bin, CAS Write Latency (CWL), and command signal mode timings on the main memory interface:

tCL = CAS Latency

tRCD = Activate Command to READ or WRITE Command delay

tRP = PRECHARGE Command Period

CWL = CAS Write Latency

Command Signal modes = 1N indicates a new command may be issued every clock and 2N indicates a new command may be issued every 2 clocks. Command launch mode programming depends on the transfer rate and memory configuration.

2.1.3System Memory Organization Modes

The Integrated Memory Controller (IMC) supports two memory organization modes – single-channel and dual-channel. Depending upon how the DIMM Modules are populated in each memory channel, a number of different configurations can exist.

Single-Channel Mode

In this mode, all memory cycles are directed to a single-channel. Single-channel mode is used when either Channel A or Channel B DIMM connectors are populated in any order, but not both.
