DESCRIPTION
The MH32S64PHB is 3354432 word X 64 bit
Synchronous DRAM module. This consists of sixteen
industry standard 16Mx8 Synchronous DRAMs in
TSOP and one industory standard EEPROM in
TSSOP.
The mounting of TSOP on a card edge Dual Inline
package provides any application where high
densities and large quantities of memory are
required.
This is a socket type - memory modules, suitable for
easy interchange or addition of modules.
FEATURES
Clock frequency 100MHz
single 3.3V±0.3V power supply
Fully synchronous operation referenced to clock rising
edge
Burst length- 1/2/4/8/Full Page(programmable)
4 bank operation controlled by BA0,1(Bank Address)
/CAS latency- 2/3(programmable)
APPLICATION
PC main memory
Auto precharge / All bank precharge controlled by A10
Burst type- sequential / interleave(programmable)
Column access - random
LVTTL Interface
Auto refresh and Self refresh
4096 refresh cycle /64ms

PIN FUNCTION
Input
Master Clock:All other inputs are referenced to the rising
edge of CK
CKE0
Input
Clock Enable:CKE controls internal clock.When CKE is
low,internal clock for the following cycle is ceased. CKE is
also used to select auto / self refresh. After self refresh
mode is started, CKE becomes asynchronous input.Self
refresh is maintained as long as CKE is low.
/S
(/S0-3)
Input
Chip Select: When /S is high,any command means
No Operation.
/RAS,/CAS,/WE
Input
Combination of /RAS,/CAS,/WE defines basic commands.
A0-11
Input
A0-11 specify the Row/Column Address in conjunction with
BA.The Row Address is specified by A0-11.The Column
Address is specified by A0-9.A10 is also used to indicate
precharge option.When A10 is high at a read / write
command, an auto precharge is performed. When A10 is
high at a precharge command, both banks are precharged.
BA0,1
Input
Bank Address:BA0,1 is not simply BA.BA specifies the
bank to which a command is applied.BA0,1 must be set
with ACT,PRE,READ,WRITE commands
DQ0-63
Input/Output Data In and Data out are referenced to the rising edge of

define basic commands
The MH32S64PHB provides basic functions,bank(row)activate,burst read / write,
bank(row)precharge,and auto / self refresh.
Each command is defined by control signals of /RAS,/CAS and /WE at CK rising edge. In
addition to 3 signals,/S,CKE and A10 are used as chip select,refresh option,and
precharge option,respectively.
To know the detailed definition of commands please see the command truth table.
Activate(ACT) [/RAS =L, /CAS = /WE =H]
Read(READ) [/RAS =H,/CAS =L, /WE =H]
Write(WRITE) [/RAS =H, /CAS = /WE =L]
Precharge(PRE) [/RAS =L, /CAS =H,/WE =L]
Auto-Refresh(REFA) [/RAS =/CAS =L, /WE =CKE =H]
ACT command activates a row in an idle bank indicated by BA.
READ command starts burst read from the active bank indicated by BA.First output
data appears after /CAS latency. When A10 =H at this command,the bank is
deactivated after the burst read(auto-precharge,READA).
WRITE command starts burst write to the active bank indicated by BA. Total data
length to be written is set by burst length. When A10 =H at this command, the bank is
deactivated after the burst write(auto-precharge,WRITEA).
PRE command deactivates the active bank indicated by BA. This command also
terminates burst read / write operation. When A10 =H at this command, both banks are
deactivated(precharge all, PREA).
REFA command starts auto-refresh cycle. Refresh address including bank address are
generated internally. After this command, the banks are precharged automatically.
