HY57V643220D(L/S)T(P)-xI Series
4Banks x 512K x 32bits Synchronous DRAM
DESCRIPTION
The Hynix HY57V643220D(L/S)T(P)-xI series is a 67,108,864bit CMOS Synchronous DRAM, ideally suited for the memory applications
which require wide data I/O and high bandwidth. HY57V643220D(L/S)T(P)-xI is organized as 4banks of 524,228x32.
HY57V643220D(L/S)T(P)-xI is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs
are synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth. All
input and output voltage levels are compatible with LVTTL.
Programmable options include the length of pipeline (Read latency of 2 or 3), the number of consecutive read or write cycles initiated
by a single control command (Burst length of 1,2,4,8 or full page), and the burst count sequence(sequential or interleave). A burst of
read or write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by a new burst
read or write command on any cycle. (This pipelined design is not restricted by a '2N' rule)

Pin Name
DESCRIPTION
The system clock input. All other inputs are registered to the SDRAM on the
rising edge of CLK.
Controls internal clock signal and when deactivated, the SDRAM will be one
of the states among power down, suspend or self refresh
Enables or disables all inputs except CLK, CKE and DQM
Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
Row Address : RA0 ~ RA10, Column Address : CA0 ~ CA7
Auto-precharge flag : A10
RAS, CAS and WE define the operation
Refer function truth table for details
Controls output buffers in read mode and masks input data in write mode
Multiplexed data input / output pin
Power supply for internal circuits and input buffers
Power supply for output buffers
