These are address bus lines which enable direct addressing of memory

(250k Q @ Vcc=Sv)

on the card. Signal AI) is not used in word access mode. The system
should NOT access memory beyond the card’s density. because the
upper addresses are not decoded.

CEI# enables Do-D7, CE2# enables Dx-DIG.

1 Pull-up OUTPUT ENABLE:

(250k Q @ Vcc=Sv)

Active low signal gating read data from the memory card.

1 Pull-up WRlTE ENABLE:

(250k 52 @ Vcc=Sv) Active low signal gating write data to the memory c‘ard.

READY/BUSY OUTPUT:

indicates status of internally timed erase or write activities. lD242
series has two types of Ready/Busy output mode; PCMClA mode and
High-Performance mode.

RDY/BSY# 0

In PCMClA mode, a high output indicates the memory card is ready
to accept accesses. A low output indicates that a device in the memory
c,ard is busy.
In High-Performance mode, the card outputs low when the card is in
default state. A high output indicates at least one of flash memory
devices in the card comes to be ready to accept accesses.

CARD DETECT 1 & 2:

These signals provide for card insertion detection. The signals are

CDt#, CD2# 0 Pull-down Ow

connected to ground internally on the memory card, and will be forced
low whenever a card is placed in the socket. The host socket interface
circuitry shall supply 10K or larger pull-up resistors on these signal

pins.

6.1 Common Memory

6. 1. 1 Common Memory Architecture
Figure 2 shows common memory architecture of ID242 series flash memory card. Device pair is consisted of two

pieces of flash memory devices. Each device has individually erasable and lockable blocks. All
blocks are divided into odd bytes and even bytes.
Each device pair and block is selected by address bits. Table 3 shows definitions of address bits.

6. 1. 2 Erase
Erase is executed one block at a time. Erasable block size is 64K bytes in byte access mode and 128K bytes in

word access mode.

6. 1. 3 Address Decoding
The higher address area of ID242 series flash memory card which goes beyond common memory area is not

decoded in common memory access. It means that the system will access to random memory address of the
memory card even if system will try to access to the memory address which exceeds memory capacity of the card.
Please do not access to the memory address which goes beyond memory capacity of the card.
As an enhanced function, the memory card enables to output invalid data (either of OOOOh or FFFFh) when system
will access to the memory address which exceeds memory capacity of the card. Please contact our sales & market­ing support to find concrete way of setting.

6.2 Attribute Memory

Figure 3 shows attribute memory map of ID242 series flash memory card. Attribute memory is contained within
the Card Control Logic. Attribute memory contains the Card Information Structure (CIS) and Component Man­agement Registers (CMRs). The CIS contains tuple information and is located at even byte addresses beginning
with address OOOOh (Please refer to section 7). The standard CIS of ID242 series flash memory card is hardwired
and is for read only. As an enhanced function, the hardwired CIS area is switchable to EEPROM so that customer
can program required CIS. Please contact our sales & marketing support to find concrete way of setting. The
CMRs are located at even byte addresses beginning with address 4000h (Please refer to section 9).
