OPERATION DESCRIPTION
BANK ACTIVATE
The SDRAM has two independent banks. Each bank is activated by the ACT command with
the bank address(BA0,1). A row is indicated by the row address A11-0. The minimum
activation interval between one bank and the other bank is tRRD.
PRECHARGE
The PRE command deactivates indicated by BA. When both banks are active, the precharge
all command(PREA,PRE + A10=H) is available to deactivate them at the same time. After tRP
from the precharge, an ACT command can be issued.
READ
After tRCD from the bank activation, a READ command can be issued. 1st output date is
available after the /CAS Latency from the READ, followed by (BL-1) consecutive date when
the Burst Length is BL. The start address is specified by A9-0, and the address sequence of
burst data is defined by the Burst Type. A READ command may be applied to any active bank,
so the row precharge time(tRP) can be hidden behind continuous output data(in case of BL=8)
by interleaving the dual banks. When A10 is high at a READ command, the
auto-precharge(READA) is performed. Any command (READ, WRITE, PRE, ACT) to the
same bank is inhibited till the internal precharge is complete. The internal precharge start
timing depends on /CAD Latency. The next ACT command can be issued after tRP from the
internal precharge timing.
