W947D6HB / W947D2HB
128Mb Mobile LPDDR
1. GENERAL DESCRIPTION
W947D6HB / W947D2HB
is a high-speed Low Power double data rate synchronous dynamic random access
memory (LPDDR SDRAM), An access to the LPDDR SDRAM is burst oriented. Consecutive memory location in one
page can be accessed at a burst length of 2, 4, 8 and 16 when a bank and row is selected by an ACTIVE command.
Column addresses are automatically generated by the LPDDR SDRAM internal counter in burst operation. Random
column read is also possible by providing its address at each clock cycle. The multiple bank nature enables
interleaving among internal banks to hide the pre-charging time. By setting programmable Mode Registers, the
system can change burst length, latency cycle, interleave or sequential burst to maximize its performance. The
device supports special low power functions such as Partial Array Self Refresh (PASR) and Automatic Temperature
Compensated Self Refresh (ATCSR).
