注意奇偶校验mezzanies仅在25 MHz主板上受支持ALSTOM NRD109475 8RDA44670G01SA44670.E软件在同一主板上支持混合奇偶校验和ECC存储板。DRAM是四路交错的，以有效地支持高速缓存突发周期。

堆叠夹层可以堆叠两个夹层板，以提供高达256MB的板载RAM(ECC)。口MVME187板和单个夹层板一起占用一个插槽。口堆叠配置需要两个VME板插槽。ALSTOM NRD109475 8RDA44670G01 SA44670.E

ALSTOMNRD109475 8RDA44670G01 SA44670.E编程注意事项口DRAM映射解码器可以被编程以适应不同的基本地址和夹层板的尺寸。口板载DRAM被本地总线重置禁用，并且必须在访问DRAM之前进行编程。ALSTOM NRD109475 8RDA44670G01 SA44670.E

Notice The parity mezzanies are supported only on 25 MHz motherboards. ALSTOM NRD109475 8RDA44670G01SA44670.E supports mixed parity and ECC storage boards on the same motherboard. DRAM is four-way interleaved to efficiently support cache burst cycles.

Stacking sandwich can stack two sandwich panels to provide up to 256MB of on-board RAM(ECC). The port MVME187 board occupies a slot together with a single sandwich board. The port stacking configuration requires two VME slots. ALSTOM NRD109475 8RDA44670G01 SA44670.E

ALSTOMNRD109475 8RDA44670G01 SA44670.E Programming considerations The port DRAM mapping decoder can be programmed to accommodate different base addresses and sandwich board sizes. Port on-board DRAM is disabled by local bus reset and must be programmed before accessing DRAM. ALSTOM NRD109475 8RDA44670G01 SA44670.E
