ABOUT THE EXPANDED MEMORY
1. Model Name:
ARPB8, DM2000 Series
2. General:
For the expanded memory (DIMM) of the said models, only "168pin EDO DIMM" has been
given in the service manual. Therefore, detailed spec for operable memory is described
below. When expanding memory in the market, be sure to check the following memory
spec.
3. Description:
<Usable expanded memory (DIMM) spec>
Type
168pin 3.3V Unbuffered DIMM
DRAM TYPE
EDO
DIMM Capacity
16/32/64MByte
Power Supply
3.3V
Access Time
Less than 60ns
Number of DIMM
Banks
1 bank (Note 1)
Refresh Rate
1k/2k/4k Refresh (Note 2)
Parity
Not provided
SPD
*
Not supported. However, it is no problem at all to use the
DIMM with SPD, but the SPD information cannot be
scanned.
Note 1: When using a 2-bank product, the capacity may be only half recognised or may
not be recognised at all.
Note 2: For the DRAM type (Row x Column) supported by the said models, there are 6
types of "12x8, 10x10, 11x10, 11x11, 12x10, 12x11". A part of the 2k-refresh
products (11x9) or 4k refresh products (12x9) cannot be used. 8k refresh
products (13x9) are not usable since they are not supported.
* SPD (Serial Presence Detect): EEPROM writing information about the access
time, type, etc. of DRAM mounted on the DIMM.
TECHNICAL BULLETIN

Sharp Electronics (UK) Ltd., Technical Services Group
For the refresh rate of DRAM above mentioned, it is not shown as a DIMM spec in most
cases, and many vendors do not disclose the DIMM spec (only usable models are
indicated). Moreover, even if DIMM has the same model name, the maker or model
number of the mounted DRAM differs depending on the lot. Therefore, it is impossible to
say definitely that the DIMM having the same model number always operates.
DIMMs whose operating has been already checked are as follows. (Only model numbers
are shown.)
