FUNCTIONAL DESCRIPTION
The GLT5160L16 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 CLK rising edge. In addition to 3 signals, CS, CKE and A[10] are
used as chip select, refresh option, and precharge option,
respectively.
To know the detailed definition of commands, please see the com-
mand truth table.

command
Read (READ) [RAS = H, CAS = L, WE = H]
READ command starts burst read from the active bank indicated by
BA. First output data appears after CAS latency. When A[10] = H at
this command, the bank is deactivated after the burst read (auto-pre-
charge, READA).
Write (WRITE) [RAS = H, CAS =WE = L]
WRITE command starts burst write to the active bank indicated by
BA. Total data length to be written is set by burst length. When
A[10] = H at this command, the bank is deactivated after the burst
write (auto-precharge, WRITEA).
Precharge (PRE)
[RAS = L, CAS = H, WE = L]
PRE command deactivates the active bank indicated by BA. This
command also terminates burst read / write operation. When A[10]
= H at this command, both banks are deactivated (precharge all,
PREA).
Activate (ACT) [RAS = L, CAS = WE = H]
ACT command activates a row in an idle bank indicated by BA.

Auto-Refresh (REFA)
[RAS = CAS = L, WE = CKE = H]
REFA command starts auto-refresh cycle. Refresh address includ-
ing bank address are generated internally. After this command, the
banks are precharged automatically. Any other command should
not be asserted until tRC is met.
