HB52D328DC-B
256 MB Unbuffered SDRAM S.O.DIMM
32-Mword × 64-bit, 100 MHz Memory Bus, 2-Bank Module
(8 pcs of 16 M × 16 components)
PC100 SDRAM

Jan. 31, 2001
Description
The HB52D328DC is a 16M × 64 × 2 banks Synchronous Dynamic RAM Small Outline Dual In-line
Memory Module (S.O.DIMM), mounted 8 pieces of 256-Mbit SDRAM (HM5225165BTT) sealed in TSOP
package and 1 piece of serial EEPROM (2-kbit) for Presence Detect (PD). An outline of the product is 144pin Zig Zag Dual tabs socket type compact and thin package. Therefore, it makes high density mounting
possible without surface mount technology. It provides common data inputs and outputs. Decoupling
capacitors are mounted beside TSOP on the module board.
Features

 Outline: 67.60 mm (Length) × 31.75 mm (Height) × 3.80 mm (Thickness)
 Lead pitch: 0.80 mm
• 3.3 V power supply
• Clock frequency: 100 MHz (max)
• LVTTL interface
• Data bus width: × 64 Non parity
• Single pulsed RAS
• 4 Banks can operates simultaneously and independently
• Burst read/write operation and burst read/single write operation capability
• Programmable burst length : 1/2/4/8
Elpida Memory, Inc. is a joint venture DRAM company of NEC Corporation and Hitachi, Ltd.

Notes: 1. All serial PD data are not protected. 0: Serial data, “driven Low”, 1: Serial data, “driven High”
These SPD are based on Intel specification (Rev.1.2B).
2. Regarding byte32 to 35, based on JEDEC Committee Ballot JC42.5-97-119.
3. Byte72 is manufacturing location code. (ex: In case of Japan, byte72 is 4AH. 4AH shows “J” on
ASCII code.)
4. Regarding byte93 and 94, based on JEDEC Committee Ballot JC42.5-97-135. BCD is “Binary
Coded Decimal”.
5. All bits of 99 through 125 are not defined (“1” or “0”).
6. Bytes 95 through 98 are assembly serial number.

AC measurement assumes t T = 1 ns. Reference level for timing of input signals is 1.5 V.
Access time is measured at 1.5 V. Load condition is C L = 50 pF.
t LZ (max) defines the time at which the outputs achieves the low impedance state.
t HZ (max) defines the time at which the outputs achieves the high impedance state.
t CES defines CKE setup time to CK rising edge except power down exit command.

Pin Functions
CK0/CK1 (input pin): CK is the master clock input to this pin. The other input signals are referred at CK
rising edge.
S0/S1 (input pin): When S is Low, the command input cycle becomes valid. When S is High, all inputs are
ignored. However, internal operations (bank active, burst operations, etc.) are held.
RE, CE and W (input pins): Although these pin names are the same as those of conventional DRAM
modules, they function in a different way. These pins define operation commands (read, write, etc.)
depending on the combination of their voltage levels. For details, refer to the command operation section.
A0 to A12 (input pins): Row address (AX0 to AX12) is determined by A0 to A12 level at the bank active
command cycle CK rising edge. Column address (AY0 to AY8) is determined by A0 to A8 level at the read
or write command cycle CK rising edge. And this column address becomes burst access start address. A10
defines the precharge mode. When A10 = High at the precharge command cycle, both banks are precharged.
But when A10 = Low at the precharge command cycle, only the bank that is selected by BA0/BA1 (BA) is
precharged.
BA0/BA1 (input pin): BA0/BA1 is a bank select signal (BA). The memory array is divided into bank0,
bank1, bank2 and bank3. If BA0 is Low and BA1 is Low, bank0 is selected. If BA0 is High and BA1 is
Low, bank1 is selected. If BA0 is Low and BA1 is High, bank2 is selected. If BA0 is High and BA1 is HIgh,
bank3 is selected.
CKE0, CKE1 (input pin): This pin determines whether or not the next CK is valid. If CKE is High, the
next CK rising edge is valid. If CKE is Low, the next CK rising edge is invalid. This pin is used for powerdown mode, clock suspend mode and self refresh mode.
DQMB0 to DQMB7 (input pins): Read operation: If DQMB is High, the output buffer becomes High-Z. If
the DQMB is Low, the output buffer becomes Low-Z (The latency of DQMB during reading is 2 clocks).
Write operation: If DQMB is High, the previous data is held (the new data is not written). If DQMB is Low,
the data is written (The latency of DQMB during writing is 0 clock).
DQ0 to DQ63 (DQ pins): Data is input to and output from these pins.
VCC (power supply pins): 3.3 V is applied.
VSS (power supply pins): Ground is connected.
