1M X 16 Bit Low Voltage Super RAM
General Description
The A64E06161 is a low operating current 16,777,216-bit super RAM organized as 1,048,576 word by 16bit and operated on low power supply voltage from 1.7V to 1.95V. It is built using AMIC’s high performance CMOS DRAM process. Using hidden refresh technique, the A64E06161 provides a compatible asynchronous interface and data can be read in 4-word page mode for fast access times. The A64E06161 has an internal register named the Configuration Register (CR) that controls the operation. The A64E06161 is designed for reducing current consumption during hidden self refresh and operating through following mode: Deep Power Down (DPD) mode, Reduce Memory Size (RMS) mode, Partial Array Refresh (PAR) mode and Temperature Compensated refresh (TCR) mode. This A64E06161 is suited for low power application such as mobile phone and PDA or other battery-operated handheld device.

Page Mode Description
The Page Mode operation takes advantage of the fact that adjacent address can be read in shorter period of time than random addresses. Write operations do not support comparable page mode functionality. The Page Mode operation can be enabled and disabled in the CR register. If the CR register bit A7 is set to a “1”, Page Mode operation is enabled. The A64E06161 provides following operation mode for reducing power: 1. Deep Power Down (DPD) mode 2. Reduce Memory Size (RMS) mode 3. Partial Array Refresh (PAR) mode 4. Temperature Compensated Refresh (TCR) mode to a ” 0”. The device stays in the Deep Power Down (DPD) mode until ZZ is driven High. If the A4 register bit is set equal to “1”, Deep Power Down (DPD) mode will not be activated. Once the A64E06161 exits the Deep Power Down (DPD) mode, the content of the CR register is destroyed and the CR register would go into the default state upon normal operation.
2. Reduce Memory Size (RMS) mode
In this mode, the A64E06161 can be operated as a reduced size device. For example, one can operate the 16M A64E06161 as a 4M or 8M memory block. Reduce Memory Size (RMS) mode can be enabled by having the appropriate setting in the CR register. The mode is effective once ZZ goes high and remains in the Reduce Memory Size (RMS) mode until full array restored by setting the CR register again. At power on, all four section of the device are activated and the A64E06161 enter into its default state of full memory size and refresh space.
1. Deep Power Down (DPD) mode
In this mode, the internal refresh is turned off and all data integrity of the array is lost. Deep Power Down (DPD) mode is entered by ZZ low and keep 10us with A4 register bit set

3. Partial Array Refresh (PAR) mode
In this mode, customers can turn off section of A64E06161 in stand-by mode to save standby current. The A64E06161 is divided into four 4M sections allowing certain section to be active. The array partition to be refreshed is determined by the respective bit in the CR register. When ZZ is active low, only the portion of the array that is set in the CR register is refreshed and the data is keep at a certain section of memory. The Partial Array Refresh (PAR) mode is only available during standby time ( ZZ low). Once ZZ is turned high, the A64E06161 goes back to operating in full array refresh. For Partial Array Refresh (PAR) mode to be activated, the register bit, A4 must be set to a “1” value. To change the address space of the Partial Array Refresh (PAR) mode, the CR register must be updated using the CR register description. If the CR register is not updated after power on, the A64E06161 will be in its default state and the whole memory array will be refreshed.

Notes: 1. OE and the data pins are in a “don’t care” state while the device is in Partial Array Mode. 2. All other timing parameters are as shown in the switching characteristics section. 3. tR applies only in the Deep Power Down Mode.
4. Temperature Compensated Refresh (TCR) mode
In this mode, the hidden refresh rate can be optimized for the operating temperature. At higher temperature, the DRAM cell must be refreshed more often than at lower temperature. By setting the temperature of operation in CR register, the refresh rate can be optimized to meet the low standby current at given operating temperature. There are four selections (+15°C, +45°C, +70°C, +85°C) in the CR register description.

tAS is measured from the address valid to the beginning of Write. A Write occurs during the overlap (tWP, tBW) of a low CE , WE and ( HB and, or LB ). tWR is measured from the earliest of CE or W E or ( HB and, or LB ) going high to the end of the Write cycle. OE level is high or low. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested. ZZ is high for Write Cycle.

Note:
1. THE BALL DIAMETER, BALL PITCH, STAND-OFF & PACKAGE THICKNESS ARE DIFFERENT FROM JEDEC SPEC MO192 (LOW PROFILE BGA FAMILY). 2. PRIMARY DATUM C AND SEATING PLANE ARE DEFINED BY THE SPHERICAL CROWNS OF THE SOLDER BALLS. 3. DIMENSION b IS MEASURED AT THE MAXIMUM. THERE SHALL BE A MINIMUM CLEARANCE OF 0.25mm BETWEEN THE EDGE OF THE SOLDER BALL AND THE BODY EDGE. 4. BALL PAD OPENING OF SUBSTRATE IS Φ 0.3mm (SMD) SUGGEST TO DESIGN THE PCB LAND SIZE AS Φ 0.3mm (NSMD)
