中文资料：
注意奇偶校验mezzanies仅在25 MHz主板上受支持ALSTOM NRD109475 8RDA44670G01 SA44670.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）。❏ MVME187板和单个夹层板一起占用一个插槽。❏ 堆叠配置需要两个VME板插槽。ALSTOM NRD109475 8RDA44670G01 SA44670.E
ALSTOM NRD109475 8RDA44670G01 SA44670.E编程注意事项❏ 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。❏ 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
英文资料：
Note Parity mezzanines are only supported on 25 MHz main boards ALSTOM NRD109475 8RDA44670G01 SA44670.E software does support mixed parity and ECC memory boards on the same main board. The DRAM is four-way interleaved to efficiently support cache burst cycles.
Stacking Mezzanines Two mezzanine boards may be stacked to provide up to 256MB of onboard RAM (ECC). ❏ The MVME187 board and a single mezzanine board together take one slot. ❏ The stacked configuration requires two VMEboard slots.ALSTOM NRD109475 8RDA44670G01 SA44670.E
ALSTOM NRD109475 8RDA44670G01 SA44670.E Programming Considerations ❏ The DRAM map decoder can be programmed to accommodate different base address(es) and sizes of mezzanine boards. ❏ Onboard DRAM is disabled by a local bus reset and must be programmed before the DRAM can be accessed.
