Features
Mobile SDRAM
MT48H32M16LF – 8 Meg x 16 x 4 banks
MT48H16M32LF/LG – 4 Meg x 32 x 4 banks
Features
• Endur-IC™ technology
• Fully synchronous; all signals registered on positive
edge of system clock
• VDD = 1.7–1.95V; VDDQ = 1.7–1.95V
• Internal, pipelined operation; column address can
be changed every clock cycle
• Four internal banks for concurrent operation
• Programmable burst lengths: 1, 2, 4, 8, and
continuous¹
• Auto precharge, includes concurrent auto precharge
• Auto refresh and self refresh modes
• LVTTL-compatible inputs and outputs
• On-chip temperature sensor to control refresh rate
• Partial-array self refresh (PASR)
• Deep power-down (DPD)
• Selectable output drive (DS)
