IC BLOCK DAIGRAM & DESCRIPTION
IC110,111,117 EM636165TS,KM416$1120DT, K4S161622D (1 Mega x 16 Synchronous DRAM(SRAM))

Symbol Type Description

CLK Input Clock: CLK is driven by the system clock. All SDRAM input signals are sampled on
the positive edge of CLK: CLK also increments the internal burst counter and controls
the output registers.

CKE Input Clock Enable: CKE activates(HlGH) and deactivates(LOW) the CLK signallf CKE
goes low synchronously with clock(seteup and hold time same sa other inputs), the
internal clock is suspended from the next clock cycle and the state of output and
burst address is frozen as long as the CKE remains low: When both banks are in the
idle state, deactivating the clock controls the entry to the Power Down and Self Refresh
modes. CKE is synchronous except after the device enters Power Down and Self
Refresh modes, where CKE becomes asynchronous until exiting the same mode.
The input buffers, including CLK, are disabled during Power Down and Self Refresh
modes, providing low standby power.

A11 Input Bank Select: A1 1 (BS) defines to which bank the BankActivate, Read. Write, or
BankPrecharge command is being applied.

ACPAIO Input Address Inputs: A07A10 are sampled during the BankActivate command (row address
A07A10 and Read/Write command (column address AOVA7 with A10 defining Auto
Precharge) to select one location out of the 256K available in the respective bank.
During a Precharge command, A10 is sampled to determine if both banks are to be
precharged (A107HIGT). The address inputs also provide the oprcode during a Mode
Register Set command:

CS# Input Chip Select: CS)? enables (sampled LOW) and disables (sampled HIGH) the command
decoder: All commands are masked when 08:: is sampled HIGH. CSI! provides for
external bank selection on systems with multiple banks. It is considered part of
the command code.

RAS# Input Flow Address Strobe: The RAS# signal defines the operation commands in conjunction
with the CAS# and WE# signals and is latched at the positive edges of CLK. When
RAS# and CS# are asserted "LOW" and CAS# is asserted "HIGH," either the
BankActivate command or the Precharge command is selected by the WE# signal.
When the WE# is asserted "HIGH," the BankActivate command is selected and the
bank designated by BS is turned on to the active state: When the WE# is asserted
"LOW," the Precharge command is selected and the bank designated by BS is
switched to the idle state after the precharge operation.

CAS# Input Column Address StrobezThe CAS# signal defines the operation commands in
conjunction with the RAS# and WE# signals and is latched at the positive edges of
CLK: When RAS# is held "HIGH" and CS# is asserted "LOW, the column access is
started by asserting CAS#"LOW." Then, the Read or Write command is selected by
asserting WE# "LOW" or "HIGH."

WE# Input Write Enable: The WE# signal defines the operation commands in conjunction with
the RAS# and CAS# signals and is latched at the positive edges of CLK. The WE#
input is used to select the BankActivate or Precharge command and Read orWrite

command:
LDQM, Input Data Input/Output Mask: LDQM and HDQM are byte specific, nonpersistent l/O buffer
UDQM controls.The I/O buffers are placed in a highrz state when DQM is sampled HIGH:

Input data is masked when DOM is sampled HIGH during a write cycle. Output data
is masked (tworclock latency) when DQM is sampled HIGH during a read cycle.
UDQM masks DQtSPDQB, and LDQM masks DQ77DQO.

DQCPDQ15 lnput/ Data l/O: The D0045 input and output data are synchronized with the positive edges
Output of CLK. The l/Os are bytermaskable during Reads and Writes.

NC , No Connect:These pins should be left unconnected.

VDDQ Supply DQ Power: Provide isolated power to DOS for improved noise immunity.(3:3V:0.3V)

Vsso Supply DO Ground: Provide isolsted ground to DQs for improved noise immunity.(0V)
VDD Supply Power Supply: +3.3V:O:3V
