82845G/82845GL/82845GV GMCH Datasheet
System Memory Controller
The GMCH can be configured to support either SDR SDRAM or DDR SDRAM memory.
DDR SDRAM Interface Overview
The GMCH can support DDR266 and DDR200 in DDR mode with SSTL_2 signaling. The GMCH
includes support for:
The bank address lines and the address lines allow the GMCH to support 64-bit wide DIMMs using
64-Mb, 128-Mb, 256-Mb, and 512-Mb SDRAM technology. The four chip select lines support up
to four rows of double-sided SDRAM DIMMs. For write operations of less than a QWord, the
GMCH performs a byte-wise write. The GMCH does not support ECC DIMMs, registered
DIMMs, or double-sided x16 DIMMs.
SDR SDRAM Interface Overview
In addition to DDR SDRAM, the GMCH can support PC133 with LVTTL signaling. The GMCH
integrates a main memory SDRAM controller with a 64-bit wide interface and 8 system memory
clock signals, each at 133 MHz for SDR SDRAM. The GMCH supports the following:
The bank address lines and the address lines allow the GMCH to support 64-bit wide DIMMs using
64-Mb, 128-Mb, 256-Mb, and 512-Mb SDRAM technology. The eight chip select lines support up
to four rows of double-sided SDRAM DIMMs. For write operations of less than a QWord, the
GMCH performs a byte-wise write. The GMCH does not support ECC DIMMs, registered
DIMMs, mixed-mode (uneven) DS DIMMs, or PC100 DIMMs.
